Jim and Connie's postwar New York building troubles keep Jim from working on his novel. Ex-WAC from Jim's army days Roberta moves in, further upsetting Connie but pleasing Jim's friend Ed. Tenant Charley, who marries tenant Eadie, loans money to Jim to help him keep the building, money which this Casanova obtains from rich widows.
