The first trailer for Oblivion did something very unusual: It hinted at the possibility of a crazy plot twist, but didn’t explain what the plot twist would be. (Whoever edited the spoiler-heavy trailers for Dream House, Terminator: Salvation, Funny People, and The Truman Show: please take note).

The new trailer provides a bit more plot info (something to do with false memories), but it still keeps its cards close to the chest.

Our best guess at this point is that the aliens have tricked Tom Cruise (playing a drone repairman) into working for them, and that Morgan Freeman, the leader of the human resistance, tries to get Tom Cruise to fight for the humans.

We’ll know for sure when the movie hits theatres April 19th.
