In this action comedy based on true events, David Ghantt (Zach Galifianakis) discovers the true meaning of adventure. He is a simple man stuck in a monotonous life. Every day he drives an armored car, transporting millions with no escape in sight. The only bit of excitement is his crush Kelly Campbell (Kristen Wiig), who lures him into the scheme of a lifetime. Along with a group of half-brained criminals led by Steve Chambers (Owen Wilson) and a faulted heist plan, David manages the impossible and makes off with $17 million… only problem is he foolishly hands the money over to this group of double-crossers and is set up to take the fall. With the bandits blowing millions on ridiculous luxuries, they leave behind a glaring trail of evidence. In over his head, David must dodge the authorities, evade a hit man, Mike McKinney (Jason Sudeikis), and turn the tables on the ones he trusted.
