The SS American has set sail from New York to London. Aboard, the lovelorn Billy has stowed away on a mission to stop the marriage of his mystery muse, countess Hope Harcourt, to the millionaire Lord Evelyn Oakleigh. Now, it is up to Billy — with the help of showgirls, sailors, and public enemy No. 13 — to find, woo, and win back his true love. Unlikely alliances arise as mischief and mayhem ensue in this madcap musical by beloved composer and Tony Award winner Cole Porter.
