Several characters are in danger.

Emmerdale spoilers follow.

Emmerdale has confirmed full details of the dramatic barn fire that will cause chaos in the Dales next week.

In recent weeks, viewers have seen Moira Dingle behaving erratically and fighting with her family before suffering a seizure.

This week, Moira’s worrying behaviour will continue, and she will have an affectionate moment with Cain’s son Nate – who she previously had an affair with.

While Nate will be horrified by the incident, Moira will be confused as to what the problem is. But to make matters worse, Caleb will oversee the whole situation.

In scenes that will air next week, Caleb tells Cain about Moira’s ‘kiss’ with Nate and he is taken aback. Moira plays down what happened, and she is angry at her husband’s shocked reaction.

Cain storms out to track down Nate, and he demands an explanation from his son. When he returns home in a rage, Moira realises he has attacked Nate.

This time Moira is furious, and intriguingly, she begins to experience déjà vu. Feeling stressed and shocked in equal measure, she slaps Cain.

Later, Ruby heads to the barn to gloat at Moira amid her struggles, but she starts to feel sorry for her when she doesn’t respond to her insults.

Moira gets more stressed and pours tractor fuel in the barn. In a twist, Ruby’s voice begins to blue with that of her old nemesis Emma Barton, and Ruby is freaked out when she raises a shotgun in the air.

Moira locks the barn and fires a warning shot, continuing to see Emma instead of Ruby. It hits a lightbulb and a spark takes hold, waiting to catch on the fuel covered barn.

The two women fight for the shotgun and Ruby receives a blow to the head. It is then that Moira snaps out of her daze and is confused about everything that has just happened.

It isn’t long before the barn becomes ablaze, and helpless Moira is unable to move, next to Ruby who lies motionless.

Meanwhile, Mack sees smoke coming from the barn and heads down when he is unable to get in touch with his sister. He and John are worried, so both go inside to help.

Cain, Caleb and Chas are also told about the fire and head to the scene. Cain is still angry with Moira, but he is still desperate to help his wife, as Chas tries to hold him back.

Several characters remain trapped in the burning barn when there is a huge explosion that throws everyone to the ground. Will everyone survive this dramatic incident?

Emmerdale airs on weeknights at 7.30pm on ITV1, and streams on ITVX.
