It's a movie with Nicholas Holt as one of those slow moving zombies. Who just looks like attractive dude with slightly abnorally pale skin and dark eye shadow. Apparently all he wants to do is *connect* with someone, but oh, well, he's dead.
Then he meets bad-ass apocalypse surviving girl, falls in love with her and gains a heartbeat and comes more and more "alive"? Then the trailer shows how all the *really evil* zombies (the one who are like mindless evil rat-like skeletons) are going to try to kill everyone and meanwhile all the human shaped zombies are catching heartbeats like it's a virus and they *come back to life* or something so they help the humans.
