The Triangle

When Jess sets sail on a yacht with a group of friends, she cannot shake the feeling that there is something wrong. Her suspicions are realized when the yacht hits a storm and the group is forced to board a passing ocean liner to get to safety, a ship Jess is convinced she's been on before. The ship appears deserted, the clock on board has stopped, but they are not alone... Someone is intent on hunting them down, one by one. And Jess unknowingly holds the key to end the terror.

Towards the end of the movie, when Jess prepares to drive off she puts the duffel bag containing her doppelgangers corpse in the trunk. During the accident scene, the doppelgangers corpse is laying on the pavement, no longer in the duffel bag. The positioning of the corpse in the road is deliberate, as Christopher Smith explains on the DVD commentary. The audience is meant to question whether the "doppelganger" has really been thrown out of the trunk and bag during the crash, or was in fact the "real" Jess who was driving - and therefore killed - in the "original" accident.
