When an unidentified hiker is found deceased in the Florida wilderness, authorities release a sketch. Multiple hikers call in claiming to have met the man. There’s only one problem – he never told them his name. It would take two years, thousands of devoted internet sleuths, and a miracle of science to identify him, and that’s when the trouble really starts.

The quiet life of a beach bum is upended by dreadful news. He sets off for his childhood home to carry out an act of vengeance but proves an inept assassin and finds himself in a brutal fight to protect his estranged family.
