Rex Dobson (Ryan Macquet) and Alice Edmonds (Claire Opperman) find themselves stranded alongside the R106, a freeway just outside Johannesburg. Waiting for help, they are abducted by a masked madman who does unthinkable things to them. Both survive, but wish they hadn't. As their stories unfold, it is clear that the truth of what happened that fateful day is far worse than anyone could imagine. Investigating the crime is Detective James Hirsch (Michael Thompson), a police officer who is used to doing things his own way. The two survivors are thrown into separate interrogation cells and Hirsch questions them relentlessly about the details surrounding the events they describe. What follows is a brutal account of what happened to the two survivors. Told in an unconventional narrative structure, The Unforgiving tosses and turns between points of view and characters as the film builds to its horrifying climax.
