Machine Gun Preacher 2011

When ex-biker-gang member Sam Childers (Gerard Butler) makes the life-changing decision to go to East Africa to help repair homes destroyed by civil war, he is outraged by the unspeakable horrors faced by the region's vulnerable populace, especially the children. Ignoring the warnings of more experienced aide workers, Sam breaks ground for an orphanage where it's most needed - in the middle of territory controlled by the brutal Lord's Resistance Army (LRA), a renegade militia that forces youngsters to become soldiers before they even reach their teens.

But for Sam, it is not enough to shelter the LRA's intended victims. Determined to save as many as possible, he leads armed missions deep into enemy territory to retrieve kidnapped children, restoring peace to their lives - and eventually his own. The explosive, real-life tale of a man who has rescued over a thousand orphans from starvation, disease and enslavement.
