When two talented acrobats are fired for fighting with unruly punks during their performance, they seek refuge with their aunt who is facing pressure to sell her house for a new real estate development. However, the situation becomes even more complicated when the developer's troublesome son, Lee Fu, gets involved and clashes with the acrobats and their unexpected ally, an American named John, who used to be Lee Fu's friend. As tensions escalate, the acrobats must defend their new kung fu school against Lee Fu's gang. The conflict eventually leads to a life or death battle, a stint in jail, a surprising decision from their aunt, a budding acting career, a possessive girlfriend, a debilitating injury, a reevaluated friendship, and the ultimate showdown with Lee Fu's avenger.
