Counterclock (2014)

Nolan Grant lives his life wandering the streets as a vagrant. Something horrible happened in his past and it's when he meets a Clocker named Danny Hughes (Hunter Miller) that he is given the chance to go back in time and change things. However, as the story progresses, we learn that every character is hiding something and although Nolan has this amazing tool at his disposal, there may be too much of a risk to change anything at all. As we pursue into a world where time-travel is possible, we discover new rules and limitations to this concept we created.
