Little Cop is a rotund little man from a family of crooks who is allowed to join the Hong Kong Police Department when they let in `handicaps.' There follows a series of comic vignettes as young Li (Eric Tsang) gets shunted from division to division, e.g. from the anti-prostitute squad, where he falls for a prostitute, to the Severe Cases section where he is assigned to track down the master disguise artist, Multi-Face. The best gag involves Multi-Face's attempt to hijack a plane to Hong Kong, only to find that the plane is already going there. His nerdy seatmate derides him for breaking the law and tells him cops will arrest him when he gets off the plane, so Multi-Face switches faces with the nerd, pulling his own face off and revealing the other guy's face underneath and putting his own face on the nerd who then has to explain to the cops what happened.
