Overbooked (2012)

Vanessa, a super posh diva, finds herself stranded on a lighthouse instead at a luxury resort. To make things worse, there is no way to get off the island until the next ship arrives the following week. This leaves her with plenty of time to get acquainted with the burly lighthouse keeper and Sebastian, a dropout, with whom she competes for the only shabby little guestroom. Material girl Vanessa vs. slacker Sebastian: Two completely different worlds collide, yet opposite attracts. Things heat up and get rather mysterious with the discovery of a dead body and the arrival of a third guest. A grotesque fight for survival begins.
