After Izzy is mugged by yobs at a cash point, an unstable Gary vows that he will never let her come to harm again - still haunted by the fact that he was unable to help his tragic army friend Quinny in Afghanistan.
Izzy's wheelchair was damaged in the attack but when it's ready to be picked up from the repair shop, Gary decides not to hand it over to his partner and instead keeps it locked in his van.
When Izzy realises that something is amiss, she confronts Gary but is stunned when he refuses to let her leave the flat - claiming it's too dangerous. The feisty factory worker tries to reason with her boyfriend but soon becomes deeply disturbed as she realises that she's a prisoner in her own home.
With the situation escalating and Gary losing his grip on reality, Izzy's father Owen comes to the door and hears her screaming for help. Can he rescue her and will Gary get the help that he needs?
These scenes air on Monday, July 25 at 8.30pm on ITV1.

Over on EastEnders, erratic Michael Moon has another surprise up his sleeve when he tries to hold out an olive branch to Jack Branning.

Although Jack is dubious over the schemer's apology, he senses that Michael is hurting and decides to rebuild their relationship again - but will the truce last?
An Walford source commented: "Michael has never felt more alone since Tyler and Eddie arrived on the Square, and now Anthony is here Michael feels even more pushed out.
"Michael wants to try and build bridges with Jack again and although it will take a long time for Jack to forgive him, he agrees to try."
