When opera singer Riley Williams agrees to sub as a musical-theater performer on a luxury Rhine/Moselle River boat cruise, she gets more than she bargained for.
Not only does she have to come up with 250 Broadway songs, she must dance with the male passengers. Dance—the subject she nearly failed in her conservatory courses, and the cause of her recent flop in an opera house. To make matters worse, she overhears two terrorists at a café in Antwerp, Belgium, discussing the transfer of deadly Agent X to the highest bioterrorist bidders.
