Boots, a girl who wears yellow rain boots even when it's not raining, and a boy called Eggs take a journey through memory and imagination following the sudden death of their friend, Peter. As Eggs dreams of asking Boots to the upcoming Favorites Dance, Boots loses herself in a world of fallen leaves, consumed by her quest to remember the last words Peter said to her before he died. "The Swing of the Sea" is a play about growing old without aging that examines the way fantasy and memory converge when we lose someone we love.
