Herman Lewis and Christine Millman have been friends for more than thirty years. When their respective mates were alive, the two couples saw each other constantly and often traveled together. As the play opens, Christine is preparing to move-tomorrow-from her apartment in New York City to Florida, where she will share an apartment with another widow. From out of the blue, Herman appears to request that she stay in the city and marry him. Christine thinks the idea is ridiculous, but Herman persists and tries to change her mind over the ensuing eighteen hours.
