Emmerdale has unveiled the first full details of its highly-anticipated factory fire storyline.

In an episode due to be shown in the coming weeks, Amy Wyatt (Natalie Ann Jamieson) and her mother Kerry (Laura Norton) will accidently start a devastating blaze which leads to the one person losing their life.

The plot will see Amy in debt to an ex-boyfriend from her past life in Belfast. The day after Bernice Blackstock's Wild West charity fundraiser, Amy and Kerry will plot to steal the money raised to pay off Amy's debt.

However, after the pair rob the cash, they discover they have been caught on CCTV and Amy decides they need to cover their tracks.

They let themselves back into the factory and sabotage the camera system before making their escape.

However, they also inadvertently start a fire which engulfs the factory . . . and Tracy Metcalfe (Amy Walsh) finds herself trapped in the building's storeroom as the blaze spreads.

Norton (36) said there will be "huge consequences" to their character's actions. "It's huge consequences because it was a tragic accident if anything like that were to happen," she said.

"And at the end of the day they think that they just started a fire, and they knew it could be bad.

"But, yes, it's huge for any character, no matter how tough-skinned anyone is or however much trouble anyone's been in before, it's awful to think that you could be responsible for that."

She added that filming for the pivotal fire scene saw shrapnel fly through the air.

She said: "It was brilliant. We had to stand back for the first one, they just sort of moved just out of the vicinity because it was too hot and there was shrapnel going everywhere.

"We got to view it and see the rehearsal, which was amazing. And we did the scene separately from the explosion as we were sort of set back from everybody.

"We were all genuinely emotional but excited at the same time."

Emmerdale airs weeknights on Virgin Media One and ITV.
