Michael (Daniel Wu) grew up in Hongkong, and his father (Richard Ng) was a construction worker. His father wanted him to follow in his footsteps, but Michael was bent on becoming an alternative music composer. Michael was sent by his father to his mistress in Beijing to let his son learn Mandarin, expand interpersonal relationships and rethink the future. In Beijing, Michael meets Pinglu (Geng Le) and his girlfriend Angelababy (Shu Qi), who also like music.

Pinglu, who loves rock music, is a rock musician who came to Beijing from other places to travel around the world. He tried to form his own full moon band, trying to break out of China and enter the world music stage with his strong musical style. On the other hand, Angelababy is a showgirl who came to Beijing from the countryside to try her luck. Lively and rebellious, she has a gentle and considerate heart in the face of her boyfriend's rock musician. But in fact, Angelababy is a moth. The more dangerous things attract her, the more she tries her best.

Michael was deeply attracted by this group of young people. He liked their persistent musical spirit and followed them all the way to the countryside. Three young people with completely different backgrounds involuntarily attracted each other and had a complicated relationship.
