This movie lost my interest in the first 7 minutes. There is a big night gathering for an engagement party at a huge home on the beach that is owned by the soon to be groom. There is a shooting on the beach (which noone heard) and a few minutes later, once someone sees his body and screams, his mother can be heard screaming over his body. So...how come they could hear her but not the gunshots? Totally not believable.
