A time traveling tranny (hermaphrodite) goes back in time and ends up having sex and knocking up their younger opposite gender self while chasing their future self in an attempt to stop their future self from setting off a bomb that would kill a mid future self. [spoiler]the child that was conceived was the time traveler. It is its own parents[/spoiler] Real movie. Had Ethan Hawke in it. I'd give it a -6/10. Was like a train wreck you couldn't turn off. Edit: it was Predestination
