Nothing gets to Taraji P. Henson's character in "Proud Mary," in theaters Friday. The professional hitwoman has nerves of steel and ice water flowing through her veins. Getting ready for "work" means packing the right pieces, and her only concern is making sure the job is done.

Until she inadvertently crosses paths with Danny, a 12-year-old who happened to be in the wrong place at the wrong time, but with the right accessories. She finds him at the scene after her work is done. Because he's been playing video games with his headphones on, he has no idea what's just happened.

Mary sneaks away, but can't quit thinking about that kid. She keeps an eye on him and eventually becomes part of his life. That's where the real story begins.

Here's the trailer:

"Like Danny, Mary was forced by circumstances to take on this life," producer Paul Schiff said in a statement. "As a child she'd been picked up off the street and trained to kill. The only love that she has ever really known is from this dark, criminal family that cared for her in return for her services as an assassin—and as she gets older that perverse relationship continues."
