2 Guns (2013) on Netflix

Robert Trench, an undercover DEA agent, takes advantage of gunman Michael Stigman's idea to rob a bank to bust him and a mob boss. However, it proves too successful with much more money seized than anticipated with Trench's forces not stopping the getaway. Complicating things still more, Stigman turns out to be a Naval Intelligence agent who shoots Trench and takes the money. The interservice debacle suddenly finds Trench and Stigman in a bloody web of corrupt clandestine rivalries as they are hunted, blackmailed and isolated for the money on both sides of the law. Now, the fugitives must work together to find a way out of this situation with no one to turn to but themselves.
