This is the moment when Gail Platt fears that her plan to stop David carrying out his revenge on Kylie's killer has ended in tragedy.
On Friday night viewers saw a heartbroken Gail find a chilling suicide video that her son had made for the family - making it clear that he intended to murder Clayton and in the process end his own life.
Desperate to foil his suicide mission she enlists Sarah and Nick's help to hatch a plan which involves locking David in the Bistro cellar until Clayton's murder trial is over.
But she has not counted on David's determination and what lengths he will go to in order to escape the makeshift prison cell and when all goes quiet behind the locked door she is horrified to find him motionless and bleeding on the stone floor.
Is this the end of David's dastardly plan or will he break free to wreak havoc and cause carnage in Weatherfield?
