Black Shark

A drifting ex-soldier turns underground fighter with the help of a just-released ex-con, pitting him against corrupt cops and hired killers now gunning for him and all those he cares about.

Two brothers compete in the world's deadliest underground fighting tournament, where they must decide whether to play by the rules or to cast their honor aside and team up to bring down the dark syndicate running the tournament.

When Andrew Briggman — a young soldier in the US Army during the invasion of Afghanistan — witnesses the murderous behavior of fellow soldiers, under the direction of a malevolent Sergeant, he faces a moral dilemma. His increasingly-violent platoon becomes suspicious that someone in their ranks has turned on them, and Andrew begins to fear for his safety. A fictionalized dramatization based on a true story.

After a mission goes wrong, only one of a group of mercenaries is left alive to avenge his fallen brothers.
