A group of teenagers, Dustin, Lucas, Mike and Will, dressed in clown costumes on a Halloween night, carried out a shocking bank robbery.Their behavior immediately attracted the attention of the police, and a fierce road chase ensued.However, in this seemingly thrilling chase, there is an incredible twist.

As the police car chased the robber's vehicle, a girl suddenly made a gesture, and then the bridge in front collapsed.The driver stopped the car in fear, but was scolded by his colleagues because they discovered that the bridge did not really collapse.It turned out that all this was just the girl's illusion. She reached out and wiped her nosebleed, revealing the tattoo on her arm, which was exactly the same as the tattoo on “11”'s body.

This incident is just the beginning of a series of adventures for them.Although they lost “11” during their adventure, their friendship was not affected.Instead, they came closer together to face the challenges ahead.

They decided to take the money and go to the arcade to play together, everyone raising funds in their own way.Mike was short of money, so he had to borrow some change from his sister Nancy.In the arcade, they are keen to compete with each other in games. The higher the score, the higher their name will be on the ranking list.Game master Dustin has always been at the top of the list, but one day, he found that his name was replaced by a man named “Mad Max”.

While they were discussing this mysterious game master, Will suddenly noticed something strange outside the door.After he walked out, he found himself in a strange space, which was exactly where he was trapped before.He was frightened and confused when a voice suddenly stopped him.He looked back and found that his friends were all around him, and the surrounding environment had returned to a normal world.

On the day before Halloween, the pumpkins at Merrill Farms were extensively vandalized.Sheriff Jim Hawkins went to investigate and found that the damage to the pumpkin at the scene was very serious, and it was not like ordinary people.When he walked to the dry seedling field, he smelled a foul smell, and there were flies and crows flying everywhere.He looked closer and found nothing strange except a scarecrow.

At the same time, Mike was punished by his parents for borrowing money from his sister Nancy and asked him to throw away two boxes of toys.Will returns home, chats with his brother Jonathan for a while, and soon becomes involved with his mother's new boyfriend, Bob.However, when Will went to the bathroom at night, he found that the otherworldly scene appeared outside the door again.He couldn't help but go out and saw the thick dark clouds, the gloomy atmosphere, the red lightning and the multi-clawed monster again.

Sheriff Jim came to a house in the suburbs. He skillfully avoided all the mechanisms and pushed the door open.At the dinner table, he saw “Eleven” and the two started talking.
