Frank Iero is one of the best assassins there is. He is paid handsomely, and he gets the job done. He doesn't let his emotions interfere with his work, and he's never even been close to being caught. That is until Gerard Way catches him red-handed with a sniper rifle in his hand and a Mobster's son lying dead on the street below. Frank can't let this information escape, so he must work with and protect Gerard from a New York mob that threatens both of their lives.
