Kevin, Sam and Rob live for FOOLPROOF, their own private club where through high tech, meticulously thought out and executed plans, they pull off the most impossible of heists -- all in theory that is. They've never actually done it for real. But all that changes when Leo, a ruthless gangster, rips off their plans for a diamond heist. Blackmailing them, Leo forces the reluctant trio to execute a robbery worth tens of millions of dollars. As they get closer to the actual heist a terrifying reality sets in. No longer do they just need a foolproof plan to pull off their heist, but more than ever, they need one to get out alive.
