 Self-absorbed Dr. Lee Johnson enlists with the Army medical corps during World War II, more out of a feeling that it s "the thing to do" rather than deep-seated patriotism. On his first day, he s put into place by  Snapshot , a sassy and attractive nurse. Their initial antagonism blossoms into romance. Lee then finds himself torn with guilt over being unfaithful to his wife, Penny, who s waiting for him back home.
