Here's the official synopsis:

Mallory Kane is a highly trained operative who works for a government security contractor in the dirtiest, most dangerous corners of the world. After successfully freeing a Chinese journalist held hostage, she is double crossed and left for dead by someone close to her in her own agency.

Suddenly the target of skilled assassins who know her every move, Mallory must find the truth in order to stay alive.Using her black-ops military training, she devises an ingenious—and dangerous—trap. But when things go haywire, Mallory realizes she’ll be killed in the blink of an eye unless she finds a way to turn the tables on her ruthless adversary.

Apparently, the director of Contagion, Ocean's Eleven, Traffic, and Erin Brockovich stumbled upon an Mixed Martial Arts matchup on television one night and was immediately inspired to build a feature film around Gina Carano.  To craft the story, he called upon his screenwriter Lem Dobbs,with whom he famously collaborated on The Limey.  Carano's making her feature debut with Haywire, but she's surrounded by veteran actors including Ewan McGregor, Michael Douglas, Channing Tatum, Antonio Banderas, Bill Paxton, Michael Angarano, and Michael Fassbender.  We're taking bets on how many of those actors are brutally beaten in the course of the movie.

Haywire is set for theatrical release on January 20, 2012.

Full Disclosure: Haywire is produced by Relativity Media, iamROGUE'S parent company.
