Tired with their exertions at the end of their tennis game, George and Ben decide to go in bathing. The girls desire them to continue playing; they refuse and manage to steal away, secure their bathing costumes, and go off to the river. The girls discover them and for a lark, Jessie steals George's suit, dons it, and substitutes her own clothes, which much to his discomfiture, George is obliged to wear. It happens that at the time the change of clothing is made, the police have received instructions to be on the lookout for an escaped woman lunatic disguised as a man, and also to arrest if seen, a burglar disguised as a woman who has escaped the officers. After many funny adventures on the part of the disguised couple they are arrested and, what promised to be a most serious affair for both, ends in a hilarious incident in the police station.
