I enjoyed this lighthearted comedy based on a true story that happened in 1997. It is about David Ghantt (Zach Galifianakis), an armored car guard who robs his employer Loomis Fargo. Because he is in love with his former work partner Kelly Campbell (Kristen Wiig), he is tricked into committing the largest cash robbery in U.S. history. He steals over 17 million dollars in this heist. David assists in helping the FBI catch the real mastermind, Steven Chambers (Owen Wilson).
