Charles King and his wife are worried about a rash of burglaries in their neighborhood, but a homemade alarm is useless when Al St.John the burglar comes around. Smashing through the house, he's confronted by King, who lets him go if he'll include a terrible coat his wife made in his loot bag. When he realizes the coat may be valuable, he chases Al around Culver City in his pyjamas and bathrobe.
