Great question — answering as the UphillTech team:
Predestination For his final assignment, a top temporal agent must pursue the one criminal that has eluded him throughout time. The chase turns into a unique, surprising and mind-bending exploration of love, fate, identity and time travel taboos. Near the end of the movie : After returning to that day, John encounters Jane, and when they begin talking, John realizes he was Jane's lover. The baby born from this "self-fertilization" is taken by the agent to an orphanage 18 years earlier. Therefore, Jane, John and their baby are the same person , revealing a predestination paradox.
