okay . she on the boat with this guy and realize he out to kill her and knock him out and and then find the reason he out to off her be this disk that get her coworker kill . so what would any rational person do . maybe conk him over the head again to make sure he really out . tie him up . look and sandra honey and you have get the chance to escape while the guy be out for only so long . until you know how long it will take you take you to escape and make sure he not able to come after you . i hate these stupid female victim role . the rest of the movie be just a series of twist and turn that be completely convolute and too unbelievable to remain interesting .
