This film is a Hong Kong version of the British Carry On films, this one specifically set in a hospital. The hospital is full of inept people, so Miss Kuk (Meg Lam) vows to the board that she will reform it. This involves the recruitment of student nurses, keeping in check some silly interns and dealing with Dr. Chen, whose wife just left him.

Bodyguard Ah Sun is sent to protect his boss' son, only to meet and fall in love with his gorgeous mistress.
