This is a romantic and bizarre movie. The story takes place on a ship full of immigrants. The protagonist's name is 1900. He was an orphan who was abandoned by his parents on a cruise ship. Danny, a worker on the ship, adopted him because the year was 1900. Danny named him 1900 and he grew up on a cruise ship. . However, the good times did not last long. Danny died unexpectedly at work, and 8-year-old 1900 became an orphan again. It turned out that the police wanted to send 1900 to an orphanage, but the clever 1900 hid it.

When everyone thought 1900 was missing, a miracle happened. One night, the passengers on the ship were awakened by the beautiful sound of a piano. They followed the sound of the piano and found that 1900 was playing in front of the piano. Everyone was moved by the sound of the piano. In 1900, because of his talent, he stayed on the ship and became a pianist, although he never became a pianist until he became an adult. Never got off the boat, but his playing skills are well known. In 1900, he met the trumpet player Marx on the ship, and music made them close friends. Soon after, the creator of jazz heard that 1900 was first-class, so he made a special trip to the ship to propose playing piano with 1900. The first two piano duet performances of 1900 were absent-minded, which made him very angry, so the third Ci Douqin purely demonstrated his skills with a strong sense of provocation. This provocation angered 1900, because in his opinion, this was not music at all, but a blasphemy against music. He performed the miracle of four consecutive performances and responded with more superb skills, which shocked all the audiences. Finally, the keys were heated by friction, and 1900 even lit a cigarette and put it in his lazy mouth.

Later, 1900 met a simple and charming girl. 1900 fell in love with her at first sight, but he could not express it in person. So, a song was recorded for the girl, but she was already off the boat. 1900 destroyed the song in frustration and threw the pieces into the trash. After the girl got off the boat, 1900 was very worried about the girl, so he decided to set foot on a strange land for love. When 1900 climbed halfway up the ship's ladder, he looked at the bustling city with tall buildings. He suddenly hesitated. This vibrant new land made him overwhelmed and unable to accept it.

Many years later, when World War II finally ended, the cruise ship was quickly bombed due to its age and disrepair. Max rushes to the dock and plays a familiar record on an abandoned cruise ship. It turns out that this is a song abandoned in 1900. Marx invited 1900 to come ashore, but 1900 could not accept this vast land and it was difficult to leave this unique home, so he refused. Finally, the cruise ship exploded in the sea, and 1900 and the cruise ship were buried in the sea.
