Come Clean (1931)

The Hardys, hoping to avoid having the Laurels drop in and spoil their quiet evening, pretend not to be home when the couple inevitably call. But their subterfuge is discovered, and to make the best of it, Stanley and Oliver go out to buy ice cream. On the way, they spot Kate, a woman wanted by the police, jump in the river. They save her, only to have her blackmail them into supporting her, or else she'll claim they tried to kill her. Back home, troubles ensue when the boys try to keep their wives from learning what they've brought home instead of ice cream.—Paul Penna
