Deadly Honeymoon (2010)

Watch Deadly Honeymoon: 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.
