Lt. Col. Hyde is forced into early retirement after 25 years of service as an officer in the British Army. To get his revenge, Hyde recruits seven other former officers for a special project. They are all in bad standing with the Army—having been forced out for quite serious indiscretions—and are equally dissatisfied and have skeletons in their closets.
The job Hyde is planning turns out to be a bank robbery. Hyde has chosen the officers for their respective specialities, qualities that Hyde needs to succeed with the robbery. Before robbing the bank itself, however, they stage a number of raids to get the weapons and trucks they need, and all goes off without a hitch. Hyde uses all of his skills and discipline as a tactical military strategist to execute the plan. The robbery is organised with military precision and everything really seems to go as planned—except for one simple error that gives them all away.
