Little Favour (not "Favor") is a short film starring Benedict Cumberbatch, Colin Salmon and Nick Moran. It follows the story of Wallace, aka "Ace" (Benedict Cumberbatch) when he is contacted by a former colleague to help him out with a deal gone wrong.

He's migrated his skill set into a lucrative business while managing to keep his secret battle with PTSD under wraps. But one day, while finally deciding to try his hand at a functional relationship, his old friend James (Colin Salmon) cashes in his chip and asks a Little Favour. How can Wallace refuse when he owes the James his life?
