Mike Locken is one of the principal members of a group of freelance spies@守护甜心国语@. A significant portion of their work is for the C.I.A. and while on a case for them, one of his friends turns on him and shoots him in the elbow and knee. His assignment, to protect someone, goes down in flames@爱的痕迹@. He is nearly crippled@莫斯科保卫战电影@, but with braces is able to again become mobile. For revenge as much as anything else, Mike goes after his ex-friend.
