A Delta Force unit attempts to escape from a pursuing group of ninja in a foreign country but most are killed and the rest are captured. The secret Ninja Army is headed by Colonel Scarf Mulgrew) an ex-British policeman and anti-American who has joined with Shiekh Ali Maksood, a Muslim militant, who plans to bring a suitcase nuke to New York. Mulgrew threatens to burn the commandos alive and use the nuke unless he is paid a ransom of 50 million dollars. Agents Sean Davidson and Carl Brackston are sent on a covert mission to rescue the prisoners and defeat the terrorists.

Sean and Carl parachute in and meet their contact Pango. While gathering information from a local operative named Freddie, they are confronted by Mulgrew and the corrupt local police headed by O'Reilly. Freddie is killed by Mulgrew but Sean, Carl, and Pango escape. Pango takes them to Dr. Sarah a Peace Corps nurse who hides them from the police. Soon after ninjas attack, capturing Sean, Carl and Sarah alive while Pango escapes, and imprisoning them in an old British fort to be tortured by Mulgrew. Mulgrew assaults Sarah and later it is revealed Mulgrew killed her father.

Joe Armstrong, a special forces commando now working as a teacher with the Peace Corps, is finally persuaded to help rescue his friend, Sean, and the others.[2] Joe convinces the local rebel group known as Sulphur Springs, a former penal colony led by Dr. Tamba, to join them and they steal engineering plans to the fort. Joe enters the fort stealthily and rescues Sean, Carl, Sarah and most of the commandos as they are being executed while Sulphur Springs also attacks the fort. Maksood's helicopter carrying the bomb is destroyed by Carl, Mulgrew is killed by Sean, and the Super Ninja is killed by Joe. Joe bids goodbye to Dr. Tamba and to Sean saying he will be at the school before walking away through heaps of dead ninjas and the debris of the destroyed fort.
