Devil's Playground (2010)

N-Gen uses human test subjects for their new drug, RAK.  A few months after the initial tests, all but one of their 30,000 subjects have had increasingly worse side effects.  Eventually the affected test subjects become violent, fast moving zombies whose bite is infectious.

Cole, a hired killer for N-Gen, is bitten by the first case subject, but acquires a few doses of the drug being used by doctors to treat the side effects. He is in search of Angela, the one test subject who was unscathed so he can bring her in for testing.

Angela is hiding out at her step brothers trying to start her life over. Her ex-boyfriend Joe is a cop who has been in jail for shooting a teenager and just got released on bail.  Joe wants to find Angela and get back together with her. And there you have your sub plot.

Along the way, Joe and Angela end up at the same garage with some friends, a couple of weasel-y strangers (there's always got to be weasels), and Cole who ends up being a huge help in fighting off zombies.

The whole group is trying to get to a helicopter pad where Angela's brother has asked Angela to meet him. Good god, how will they get past the zombies?  Will the weasels cause the death of the others? Will Cole turn into a zombie? Will Joe and Angela get back together? Will they ever get to the helicopter? Will Angela try to get to a lab for testing to figure out why she's immune? And why are the zombies doing free running?

I'm not sure how I feel about this one. I saw it last year and was disappointed. But when I watched it again, I thought it was okay but kind of depressing. Also the guy on the cover reminds me of zombie Jerry Seinfeld, and that just bugs me.
