When Margaret Carlson finds herself about to be replaced at the Harperville Bank by a computer, she turns to her only relative Walter for help. Her nephew must leave town, however, and the Westins invite Maggie to spend the night. She sneaks out in the night, followed by Dan, who tails her to a high-stakes poker game. The Westins confront Maggie, who admits that she tried to win enough money to retire, originally staking her game with funds "borrowed" from the bank. Now the Wesins must find a way to return the money to the bank before Maggie's indiscretions are made public, a plan complicated by a bank robbery.
