Six weeks later Poirot is in Egypt, He sits by the Sphinx to enjoy tea and a cake when he notices a man flying a kite on the pyramid

He goes to admonish the man until he sees it is his old friend Bouc

He is elated to see Poirot, and brings him to meet his mother Euphemia She is unimpressed with meeting Poirot and focuses more on her painting of the pyramid

Bouc brings Poirot to the First Cataract Hotel, where they attend a party in honor of the newlyweds Simon and Linnet

Among the guests are Euphemia, Salome and Rosalie, Linnet’s maid Louise Bourget, Linnet’s godmother Marie Van Schulyer and her nurse Mrs. Bowers and Linnet’s Cousin Andrew Katchadourian who oversees her will, and Dr. Linus Windlesham, Linnet’s former lover

Bouc tells Poirot how Marie leans toward communism and hates how wealthy Linnet is but Mrs. Bowers covets her wealth as does Louise

while Andrew is a slippery fish that nobody but Linnet trusts

The celebration is brought down by Jackie’s surprise appearance which is an occurrence that has been going on since Simon left her for Linnet

While touring the area, Linnet and Simon approach Poirot and ask him to investigate Jackie since her constant stalking of them, has made Linnet worried and uncomfortable

Poirot finds Jackie and speaks to her learning that Linnet has always cast a shadow over her

Jackie had been cast in the school play, Antony and Cleopatra but their teacher replaced her with Linnet

Jackie believes Simon still loves her and she is also carrying a 22 caliber gun in her bag

Poirot brings this information to Linnet and Simon suggesting they go home and start their lives, but Simon opts for a different solution

The next day, Simon invites the guests onto his yacht the SS Karnak to continue enjoying the festivities

Linnet later finds Poirot in his room and tells him that she does not trust any of the guests

Poirot sees as Andrew approaches Linnet to sign for the acquisition of property, which makes Mrs. Bowers unhappy

Rosalie chimes in which makes Andrew back off

Later that night, while the guests are partying

Poirot and Bouc chat with Bouc telling Poirot that he is in a relationship with Rosalie  and is very much in love with her but he is hoping for his mother’s blessing

He also notes Poirot’s attraction to Salome and encourages him to find love

The party later stops at Abu Simbel

While there Bouc tries to tell Euphemia about his relationship with Rosalie though she expresses her disapproval

Regardless, he is glad, that he no longer feels the need to hide their romance

Poirot also talks to Salome who tells him he wears a mask

Not long after Simon and Linnet are together when they are nearly crushed by a falling boulder

Moments later a sandstorm forces the guests to take cover

After everything settles they board the boat again to find that Jackie has made it onboard

Simon says they cannot do anything since she has a paid ticket to board

The guests have dinner with Simon and Linnet planning on leaving the following morning

Poirot has some champagne and feels nauseous

He goes outside and finds Jackie with the two of them talking about their failed loves

Poirot mentions that Katherine was killed in an explosion, and the loss broke him into what he is now

After Poirot goes to bed Jackie finds Simon and Linnet  the two taunting her over how many times they made love that day

After Linnet goes to bed, Simon and Jackie argue leading her to pull out her gun and shoot Simon in the leg

She becomes mortified at what she has done and throws the gun to the side

Mrs. Bowers tends to Jackie as she gets hysterical while Windlesham tends to Simon’s leg

The following morning, Louise enters the couple’s room and screams in horror Linnet is dead with a bullet hole in her head and It is said that she was murdered in her sleep

Additionally, a valuable jewel necklace that Linnet was wearing  has been stolen

Although Jackie is the prime suspect Mrs. Bowers insists that she never left the bed overnight

Simon sees his wife’s body and wails in agony

After Linnet’s body is removed Poirot has help from Simon and Bouc to interrogate the guests

They start with Louise who tells the men that she was previously engaged and set to leave Linnet’s employment after her marriage but Linnet caused Louise’s fiance to break it off after she offered to pay off his debts in a test of his affection for her

Poirot and Bouc speak to Windlesham who admits that he still carried a torch for Linnet and contemplated suicide after learning of her engagement

He was original Lord Windlesham but wished to pursue a career in helping others

The men then talk to Andrew who reveals that the contracts he intended for would have cost Linnet her money and estate

Andrew is also revealed to be carrying a 45 caliber gun

Bouc then gets Marie and Mrs. Bowers in for interrogation

It is revealed that Mrs. Bowers came from a wealthy family but Linnet’s family forced them off their land, during the Great Depression

Shortly after Jackie’s gun is fished out of the water wrapped in Marie’s missing scarf and shown to have a bullet hole in it

The gun is missing two bullets not counting the one Jackie shot Simon with

Poirot speaks to Salome who reveals that she did not previously get along with Linnet due to her having once complained about being in a pool with Salome a woman of color as a result of an upbringing by Linnet’s terrible father but later on Rosalie and Linnet got along quite well

Salome also happens to be carrying a gun like the one Jackie had

Euphemia interrupts by announcing that she found Linnet’s necklace in her room

After investigating Euphemia’s room a confrontation occurs where Poirot reveals that Euphemia hired him to spy on Rosalie to see if she was really good for Bouc

Poirot says Rosalie is a good person for Bouc but Rosalie is angered by Poirot’s revelation and berates him

He follows her but the two soon discover Louise’s body in the water wheel

Her throat had been cut by a scalpel missing from Windlesham’s collection of knives and Money is also found in her person

Poirot notices blood splatter on the wall slightly covered by a potential witness to Louise’s murder and The guests lock themselves in their rooms for safety

Poirot conducts one more interview with Simon and he begins to interrogate Bouc, who is stunned, that his friend is accusing him

He figures that Bouc had found Linnet dead and that he was the one who stole her necklace and planted it in Euphemia’s room to have her framed, so that he and Rosalie can be free from her

Bouc had also witnessed Louise trying to bribe the killer before she was murdered and Bouc threw his coat into the river since it was covered in her blood

Before he can reveal who he saw a gunshot rings out and hits Bouc in the throat killing him

Poirot chases after the killer, but fails to catch him he then has the guests locked in the bar with the help of the crew as he is ready to put the killer in their place

Poirot knows that Andrew was the one who pushed the boulder that almost killed Simon and Linnet

which he admits was an act of desperation but he says he did not kill anybody

It is revealed that Linnet’s killer was Simon and that he was working with Jackie who is the mastermind behind everything

They planned for Simon to marry Linnet and take her fortune after her death

Jackie shot Simon with a blank and after he shot Linnet he shot himself for real and used Marie’s scarf to silence the gunshot

He also stole red paint from Euphemia to fake the injury before actually shooting himself

Simon got rid of the gun but because Louise was a witness

Jackie killed her and then killed Bouc  because Simon gave her a signal just before he could reveal Jackie’s identity

The two lovers realize they are caught and aim a gun at the guests Seeing no other options

Jackie kisses Simon one last time before she shoots him in the back the bullet hitting her too and They die in each other’s arms

The guests leave the boat and Windlesham says he will continue his work in Africa

Euphemia and Rosalie still dislike Poirot, but are thankful for finding Bouc’s killer, Salome also admits to Poirot that she had an interest in him

Six months later in London, Salome is performing at the same nightclub from earlier

Poirot attends, showing that he shaved his mustache to reveal his scars and He watches Salome perform

Death on the Nile.
