Playboy barber, Happy Chan, opens up a fashionable news salon, right next door to an old-fashioned Shanghai barber shop. The owner, Chuk, is furious as this new development and creates a disturbance for Chan and his colleagues during their grand opening ceremony. Meanwhile, Chuk's pretty daughter, Ying, is forced to keep the peace. Chan and his friends all attempt to woo Ying, but end up getting drunk and falling asleep in her bedroom. Later, Ying discovers that she is pregnant, but no-one can remember which of the trio did the deed. Chan and his friends aspire to do the right thing, banding together to support her during her pregnancy until the true identity of the father can be determined. When the baby is born, it is discovered that all the prospective parents have the same blood type, and confusion begins anew.
