Entangled

Four brilliant university students experimenting with time travel confront their doppelgangers from the future. One night Loretta is killed in a tragic accident, and reappears five months later with no idea that she is supposed to be dead. What begins as the ultimate validation of their quantum physics theories takes a sinister turn when it comes to light that two versions of a person cannot survive in the same plane of existence without one lethally draining energy from the other. So, how do you kill your better half, and who can really be sure which one has triumphed? (Whistler Film Festival)
