On Saturday nights, the Pier Ballroom in Swansea is the place to be. As the girls and boys gather, we are introduced to Lily, an evacuee unclaimed by her family at the end of the war; to Judy, taught independence by her war widow mother; for Katie, the product of a marriage between a drunken, violent father and a coward, beaten mother; and for the spoiled, willful Helen. It is an evening that fuels jealousies and sows the seeds for friendships, confidences, and romance.
