For me it has been and always will be a classic British war film. Wonderful cast, huge amounts of top quality action, supervised by the legendary Bob Simmons. It stands the test of time and the story of the action scenes deserves to be told. A British businessman, Stewart Grainger, seeks to overthrow a vicious dictator in central Africa. He hires a band of mercenaries in London and sends them in to save the virtuous but imprisoned opposition leader who is also critically ill and due for execution. Just when the team has performed a perfect rescue, Grainger does a deal with the vicious dictator leaving the mercenary band to escape under their own steam and exact revenge. Roger Moore plays Shawn Fynn a smooth, Irish mercenary‌.yes Roger Moore plays an Irishman! I know‌ still moving on. He has just killed the local Mafia Godfathers nephew and the biggest contract London has ever seen has been put out on him. He is hiding out above a casino when the heavy mob arrives.
