predestination (2014)

It's a simple movie. Basically, the lady takes her own virginity, and gives birth to herself, hence, being her own parents. She loves herself and misses her boyfriend (who btw is again the lady who started it all). She meets some random time travelling geek (who again, is the same lady). They try to stop a person who is gonna commit some crime. And guess what? The criminal is also her. See..... Simple!

Ooops.... SPOILER ALERT!
