I will admit that after my first viewing I was slightly confused by the story of Push because it was a little hard to follow for me. However, after rewatching it once more (okay, twice if you count once with the commentary track), I can finally say that I think I get it.
Push creates an interesting world involving people with powers, including a telekinetic “mover,” Nick (Chris Evans), and girl who can see the future, or a “watcher,” named Cassie (Dakota Fanning) as they search for Kira (Camilla Belle), a girl who is able to bend people to her will by giving them false memories. However, they are not the only ones searching for her. Division, a government based organization, is also looking for Kira because she is the first person with abilities to survive a unspecified drug injection, as well as break out of the facility with a syringe full of it.
