Danny Trejo is Frank 'Bullet' Marasco, the toughest undercover cop in LA. Whether busting bad guys on the streets or in the underground MMA, nothing's off limits to get the job done. This no-holds-barred action thriller, packed with typical Trejo humour, sees the body count just keep rising as the hard-as-nails cop takes on a ruthless cartel in a race against time to save his family. Years earlier Bullet put notorious drug baron Carlito Kane's son behind bars. Now the ruthless Kane (Jonathan Banks) hatches a twisted plan to save him by kidnapping Bullet's grandson - but he's - messed with the wrong guy! Kane and his men are about to learn that, when the stakes are high, all it takes is one Bullet.
