Two worlds collide in Corriedale

One hour. One night. Everything changes.

In an ITV soap first, the worlds of Coronation Street and Emmerdale collide in a catastrophic, life-changing hour-long special.

It begins with Debbie Webster's dramatic wedding to Ronnie, where a desperate, drink-fuelled Carl speeds away with Debbie in the car.

Simultaneously, Becky, fleeing her past with Lisa and Betsy, loses control of her vehicle, triggering a multi-car pile-up on a stormy road between Hotton and Weatherfield.

The minibus carrying wedding guests, including Billy, Theo, Todd, David, pregnant Shona, Steve, and Tracy, heads towards the crash. Can Billy steer them out of danger?

With a drunken Carl careering out of control on the wet road, is he about to put more lives at risk?

Elsewhere, the desperate love triangle between Aaron, Robert, and the vengeful John Sugden culminates in chaos, as Aaron is held at gunpoint.

Hot on their heels, Kit and Carla arrive to save lives and pursue fugitives.

As Cain and Moira take Jacob and Sarah to the airport, they're blinded by Mack, in his car with Charity, flashing his lights.

Cain desperately tries to avert disaster when Mack's car crashes nearby.

In the queue of traffic, a mysterious van pulls up, concealing a terrified, bound woman.

The episode ends at Hotten General, where the injured arrive, but life will never be the same, and the aftermath of the crash gives rise to fear, murderous intent, death, destruction, closely-guarded secrets, and lies.

Corriedale airs Monday 5th January at 8pm on ITV1
