Kung Fu meets disco in Singapore. Hock is a grocery clerk longing for a motorbike. He lives with his parents and sister; they idolize his younger brother, Beng, a medical student calling himself Leslie. Hock loves Bruce Lee; he works out and imitates his moves. When Hock sees a cheesy local version of "Saturday Night Fever," he gets the disco bug, taking his pal Mei to nightly lessons in hopes of winning a contest and buying the bike. He's blind to Mei's falling in love with him, and, at the last minute asks another woman to be his partner in the contest. Meanwhile, Beng reveals a personal secret to his family and a crisis ensues. Hock, Beng, Mei and her rival: it's Night Fever.
