From the show:

Swing! tells the story of Adrianna, a factory worker in the 40’s who is holding down her husband Butch’s factory job while he’s at war. Once he returns home, both Adrianna and Butch feel like they don’t fit into their old lives. When she meets Janine, Adrianna rediscovers old passions that she put away when she was first married. While her feelings blossom for Janine, Adrianna‘s love for her husband is also rekindled. Adrianna’s difficult choice in a time of forbidden love fuels this passionate musical journey. Featuring songs including “Swing Sisters,” “You’re a Stranger to Me,” “Fritz’ Bakery,” “Safe & Warm,” and the humorous “Be Mine.”
