Set in a tenement boarding house, a lonely confirmed bachelor occupies a room across the hall from a dour spinster. Children run amok in the hallways playing pranks. Believing the bachelor perpetrated one particular prank, the spinster woman enters his room to confront him. She is followed by a neighbor child. Meanwhile, the other children have stolen a scarlet fever quarantine sign and posted it on the bachelor's door. The police, unaware that the quarentine sign is a prank, enforce the confinement. But aided by the sweet disposition of the toddler quarantined with them, the icy relations between spinster and bachelor begin to thaw, . . .

Adonese is returning home from seeing the woman he is courting, and he is driving around a corner when his car accidentally brushes against the tramp 'Faithful' and knocks him over. Feeling sorry for him, Adonese helps him up and buys him a new suit of clothes. The naively innocent Faithful reads too much into this gesture, and he begins to follow his benefactor everywhere, expecting to receive future gifts.
