Only Fools Rush In - Wikipedia

The film follows Wu Renyao[a] (nicknamed Ah Yao), a young motorcycle enthusiast who begins to bond with his estranged father Wu Renteng who he has not seen in many years.[6][10][11]

Walking at night he strolls into a restaurant where he sees young waitress Zhou Huansong. Attempting to put on a song for her on the jukebox he is interrupted by Zhou Huange. Yao sits down and Huange follows him, they get into an argument and Yao punches him. Huange reveals himself to be the brother of Huansong, also a leader of a motorcycling gang.

The two become friends and seeing Yao's talent with riding joins the group. This allows him to get closer to Huansong. They get into a drag race with a rival gang, who sabotages their bikes, throws things onto the track and cheats their way through it. Yao is about to win it for them when he accidentally crashes into a teammate who was going the wrong way.

The group opens a nightclub but not before Huange incurring a lot of debts from loan sharks. They meet Mr. Showta, a successful businessman from Guangzhou with great connections. Meanwhile, the local police is planning to intercept them at their next drag race as they have been illegally riding on dangerous roads.

The male members of the group go swimming in the ocean late at night when there is mist. Suddenly a cargo ship appears out of nowhere. Huange is swept under it and apparently drowns. All the debt that he incurred is now billed to Huansong.

Yao is chased by policemen, then at a sharp corner narrowly avoids crashing into a truck with sharp steel bars. He deliberately turns back and stops the police motorcycle from hitting the bars, earning himself a friend in the force.

Yao and Huansong embark on a journey to the city of Guangzhou to try and start a new life together.[12][13][2][14] They find that the address Mr. Showta gave them is the Canton Tower, where he works as a maintenance technician. Unaware of the laws prohibiting motorcycles in the city of Guangzhou, theirs is seized and they are left with no money.

The two separate and find odd jobs, meeting occasionally but not advancing their relationship. Huansong goes back to being a waitress and Yao finds a job doing motorcycle stunts at a local amusement park.

The policeman whose life Yao saved says he will get a lighter sentence especially because he is helping Huansong pay back her brother's debts. At his job, Yao's boss gets him to be a stuntman taking the place of a more popular motorcycle rider, Miaohu, doing a huge jump at a stadium (and they will secretly switch through a trapdoor). Yao and his old gang friends meet at a restaurant where Huansong happens to be a waitress. She has a big gift for him (she saved up to buy him a motorcycle) but Yao tells her he can't make it.

Yao's boss and Miaohu get in a car accident on the way there so Yao has to do the whole stunt by himself. He wears a propellor that Huansong gifted him for good luck. Just as he is landing, he slips, the motorcycle crashes, igniting a huge fire.
