War veteran Colonel Lee Gunner takes his two sons on a camping trip with their uncle Jon, to reconnect with them after being at the battle front for so long. The trip goes awry when Jon stumbles over a tripwire and sets off an explosion, alerting a gang of violent bikers in the midst of a massive drug operation. Not anticipating Gunner's elite combat skills, the gang members are taken out one by one. The boys try to go for help, but end up right in the arms of Dobbs, the son of kingpin Kendric Ryker who runs the organization from prison. With no one but himself to turn to, an enraged Gunner wreaks havoc to rescue his two sons, until he gets to the top and confronts Ryker.
