He immediately bows his head. He tells Clara that his name is Captain Phillip and that her mother, Marie Stahlbaum, is the queen and Clara is their princess. He tells Clara it’s dangerous to cross the bridge as it is the fourth realm and there is a war going on. Clara says she has to go that way anyway and orders him. He takes Clara to the other side on a horse. Clara sees the same mouse there and Clara runs after it. As soon as Clara approaches the mouse, it goes under the ground.

The pageant begins. That pageant is about his mother Marie. How her mother discovered this world. She sees all the realms one by one including the fourth realm. Sugar Plum tells her that before her mother’s discovery, they were all just toys, and children play with them. But her mother gave them life and made him. She takes Clara to another room where she shows Clara the engine built by Marie, with the help of which she has created all these worlds and infused them with life.

After which emotions like happiness, sadness, anger, and love emerged in them. Sugarplum adds that according to their spies, Mother Ginger is on the warpath. The engine is the only way they can protect themselves by building an army. But there is a key in it which is held by Clara’s mother. Without it, it does not work.

She wishes her mother with her so she could tell her if she is doing the right thing or not. A star breaks from the sky and passes through its sky. She hopes that she is doing the right thing. The next day Clara prepares the army. She is in military uniform. Sugar Plum is also there. She says that she cannot join her due to some personal reasons and she goes into the palace. The soldiers who stopped Clara while she was coming into the palace are also standing and volunteered to join. Clara tells the army to leave and walks out of the palace. They go in search of the mouse king in the forest. They arrive at Mother Ginger’s clown. The whole army is afraid to go inside. It is extremely foggy inside. Clara dismounts and walks in by herself.

Clara is disturbed to see that the Music box has a mirror on the other side. Clara doesn’t understand anything. She gives the key to Philip and tries to leave on her own, but Philip stops her. They both go to the palace. Sugar Plum is extremely happy to receive the key. She immediately turns on the engine. She immediately orders put tin soldiers on the platform.

Sugarplum’s ugly face emerges and she orders the tin soldiers to arrest Clara. Clara, Philip, and the other two regents are arrested and locked in a room.

Suddenly, seeing her in the mirror, her mind clicks and she understands what her mother is saying. She asks Philip for help. Drops a chandelier from a rope. They all come out. Clara ties herself with the rope. On the other hand, tells Philip to throw the rope over the pole according to the laws of physics and she jumps. The rope slips through the pole and they all come down. Clara and Philip are hiding in the room watching Sugarplum. Suddenly a mouse comes. It is as if the mouse wants to say something to them. Clara understands and asks the mouse for a way to the engine room. The mouse takes them through the underground sewers to the engine room. Clara tells Phillip to go to Mother Ginger and tell her about the battle and climbs off the side of the hill herself and turns off the engine. Philip approaches Mother Ginger and tells her everything. Ginger is coming towards the palace. Clara tries to sneak into the engine by distracting tin soldiers with the help of toy mice in the engine room. On the other hand, Sugar Plum soldiers attack mother ginger’s clown. The clown manages to keep them busy for a long time. In the engine room, the tin soldiers discover Clara’s presence. The clown is shot down by the soldiers, but Phillip comes out in Ginger’s place. The soldiers are near to catch Clara but Ginger arrives and stops them. Sugarplum is waiting for ginger but Philip comes out from the clown. Sugarplum looks towards the engine and she immediately comes to the engine room and captures Ginger with the help of tin soldiers. Clara hides under the engine. She modifies the engine and comes in front of Sugar plum. She explains to Sugarplum that her mother would never want that, but she doesn’t agree and said that her mother was their queen and the queen left her people alone. Meanwhile, in the forest, the soldiers are near to killing Philip. Sugarplum tells the soldiers to put Ginger on the platform. As soon as she runs the engine. Beam turns to Sugarplum instead of ginger and turns her back into a toy as she watches. Along with this, tins soldiers also lost their lives. Clara and Ginger hug each other.

A feast is laid for Clara the next day. Everyone is very happy. Philip comes to drop Clara off. Soldiers are given duty at the place of Philip. Philip asks Clara if she will come to Realm again. Clara says she will come but Philip should come to her world and meet her family. They both say goodbye to each other and Clara comes back.
