It's been getting creepier by the week but tonight What Remains is set to reach new heights. We've been promised a 'chilling conclusion' to the four part drama and, from what we've seen already at least' we're sure it won't disappoint.

He's determined to discover the truth about Melissa's death, even if nobody else is willing to help him.
