"War veteran Colonel Lee Gunner takes his two sons on a camping trip with their Uncle Jon, to reconnect after so long on the front lines," reads the official synopsis. "The trip goes awry when Jon trips over a tripwire and causes an explosion, alerting a gang of violent bikers caught in the middle of a massive drug trafficking operation. Unprepared for Gunner's elite combat skills, the gang members are picked off one by one. The boys try to get help, but end up in the arms of Dobbs, the son of prison kingpin Kendric Ryker. With no one to turn to but himself, an enraged Gunner wreaks havoc to save his two sons, until he reaches the top and confronts Ryker. You can't mess with Gunner."
