Two friends who are taking part in a murder mystery game on board a luxury liner suspect there might be a real killer among the guests.

On a Caribbean cruise, Jenny is marooned on a beach with her rock and roll idol. Deliriously in love with the idea of time alone with him, she manages to hide the fact that they're a stone's throw away from their resort.

Handsome silver spoon Texan Trevor Forrest can't always control his tendencies to flirt and gamble, even on honeymoon cruise to Tahiti with Lindsey Ross Forrest, which may compromise their business ambitions. The ship captain asks FBI agent Gwen Merced, on cruise, to investigate discretely when Trevor goes missing, probably fallen or pushed overboard as blood traces are found. It's unclear whether the Hungarian business trio Luka, Max and Ben are innocent flirtatious gamblers like Trevor or criminals, but others have hidden agendas too.
