Rambo (2008)

Having long-since abandoned his life as a lethal soldier, John Rambo (Sylvester Stallone) lives a solitary life near the Thai border. Two weeks after guiding a missionary (Julie Benz) and her comrades into Burma, he gets an urgent call for help. The missionaries have not returned and although he is reluctant to embrace violence again, Rambo sets out to rescue the captives from the Burmese army.
