Emmerdale viewers will witness dangerous scenes on the ITV soap next week, as Cain Dingle and newcomer Mackenzie go head-to-head.

Following an upcoming kidnap plot, a revenge-fuelled Cain will threaten to murder Moira Dingle's estranged brother after his arrival.

He issues a sinister threat promising he is not to be messed with, after he is attacked and held to ransom by the troubled newcomer.

Ahead of a "dark" family secret being revealed about him and his sister, he gets on the wrong side of her ex Cain leading to a deadly clash.

After seeing him in the village, Cain warns his new enemy away for good - telling him if he doesn't go he will kill him.
