Coronation Street’s Theo Silverton and Todd Grimshaw both face questions from friends and neighbours later this month after a shocking incident in their flat. Another worrying moment for their dark relationship is about to air in a special single-storyline episode, told entirely through Todd’s hidden spycams, police bodycam footage and CCTV.

The special edition airs on Monday 15 December, as the police arrive at Theo and Todd’s place following reports of a domestic disturbance. Then in the aftermath later that week, Theo struggles as his relationship is now under public scrutiny.

The day after the catastrophic incident at home, Todd cleans up the breakages around the flat as he tries to make sense of the events that took place.

Meanwhile, Bernie Winter discloses that she saw the flat in total disrepair, meaning that there is likely more to the story than Theo and Todd have been making out.

After hearing Bernie out, George Shuttleworth feels deeply concerned by her words. Will George find a way to get through to Todd about his life behind closed doors?

“Todd is starting to sense real danger, rather than a fixable situation, but he’s now so far in that he’s trapped,” reveals Gareth Pierce, who plays him.

“There is also shame locking him in. We are seeing moments, for instance at A&E after the mirror incident, where he might decide to confide in someone, but he’s too ashamed of the situation he’s found himself in and the extent to which he’s been duped…”

Later, George and Christina Boyd turn up at the flat for a meal with Theo and Todd, who do their best to keep a smile stitched onto their faces.

Eager to extend a hand, George offers Todd the opportunity to start fresh and return to his job at Shuttleworth’s – but will he accept with Theo’s eyes on him?

As George keeps up conversation, he also seizes the opportunity to grill Theo and Todd for the truth about their altercation. In fact, George even goes as far to reveal that Bernie informed him about the worrying state of the flat.

Will George suss out that something sinister is going on right underneath his nose – or will Todd remain in as much danger as before the couple came to visit?

“The physical abuse is fast becoming normalised and happening nearly every day,” adds Gareth. “Because of Theo’s effective isolation of Todd, there is no release or support around him.

“There is a high risk of Todd being badly wounded, or boiling over in retaliation, so the stakes are increasingly high. He is fast approaching rock bottom, and the question will become whether that might ignite the fire to find a way out…”

With Theo’s reign of terror at its peak, just how much trauma will be inflicted on Todd on the fateful night that the police arrive? And is there any route to safety in sight for him?
