Bad Ass - 2012

Plot: A Vietnam veteran who becomes a local hero after saving a man from attackers on a city bus decides to take action when his best friend is murdered and the police show little interest in solving the crime.

Story: Decorated Vietnam hero Frank Vega returns home only to get shunned by society leaving him without a job or his high school sweetheart. It's not until forty years later when an incident on a commuter bus (where he protects an elderly black man from a pair of skin heads) makes him a local hero where he's suddenly celebrated once again. But his good fortune suddenly turns for the worse when his best friend Klondike is murdered and the police aren't doing anything about it.
