Backtrace

A heist-gone-wrong in a quiet town results in multiple deaths and a survivor, MacDonald, whose wounds left him unable to remember where $500,000 is stashed. When a mysterious trio break MacDonald out of a mental hospital to recover the cash, they inject him with an experimental serum that sends his mind careening into other eras and revealing the secrets of his mind. As a local cop (Stallone) and an FBI agent close in, MacDonald fights to recall the robbery before a long-forgotten enemy follows the clues and catches up to him.
