In this murder mystery musical, trouble comes in pairs on a cargo ship, when two brawlers come aboard and two female stowaways are subsequently discovered.
For Kevin, a shy teenager, being bullied is part of everyday life. But one day an older guy, Benny, comes to his aid. Impressed by Benny's self-as-sured appearance, Kevin seeks his company from then on, and increasingly idolizes him. But Benny's intention is not to protect the younger boy, quite the contrary.
