Annual fundraiser Stand Up To Cancer takes over at Channel 4 tonight with Davina McCall, Maya Jama, Alan Carr and Adam Hills hosting proceedings.

The darkly comic serial killer series returns for a third time, now with the fresh twist that Joe's (Penn Badgley) wife Love (Victoria Pedretti) is just as unhinged as he is.

Now living in the San Francisco suburbs as new parents to a baby boy, the couple are unable to shrug off their murderous impulses as they find new enemies amongst their rich neighbours.

I Know What You Did Last Summer - Amazon Prime Video
