The National Sanshou (Martial Arts) Competition is taking place in a certain city, and young boxer Xiao Hai (played by Yuan Dao Dadi) is becoming increasingly courageous in battle, having stood out in the preliminary competition. However, Xiao Hai's coach Hai Dong (played by Yuen Biao) recalls the initial situation, realizing that if it weren't for the earnest plea of Xiao Hai's music teacher Lily (played by Li Bingbing), he would have missed this promising newcomer to the martial arts world during his boxing career.
Xiao Hai's father Tian Ming (played by Zhang Guoqiang) is also an excellent Sanshou practitioner who supports Xiao Hai's study of martial arts. But after meeting Hai Dong, Gong Min (played by Meng Jiahui) stops Xiao Hai from attending the youth palace to learn Sanshou. It turns out that they had been childhood sweethearts. After Hai Dong won a match and proposed to Gong Min, she shyly accepted amidst cheers from everyone present. However, unbeknownst to all, Tian Ming, who secretly loved Gong Min, was heartbroken. Before Gong Min could inform Hai Dong about her pregnancy, he left to participate in the national Sanshou competition and then disappeared without a trace...
Now, as Hai Dong and Gong Min unexpectedly meet again, Tian Ming, Xiao Hai, Gong Min, and Lily are all worried about the sudden changes.
