There's even more tension between the Dingles and Joanie Wright on Emmerdale as they clash bitterly at the factory.
The trouble all centres around Joanie's engagement ring, which 'goes missing' shortly after Zak's recent decision to propose to her.
When Joanie (Denise Black) discovers that a jealous Lisa was involved in the disappearance of the ring, it leads to a tense and bitter showdown between the two women while they're at work.
Unsurprisingly, Belle (Eden Taylor-Draper) steps in to defend her mum, but when she goes too far with her vicious tongue, Joanie loses patience and slaps the outspoken teen.
Zak walks in just in time to see the violent encounter, but whose side will he be on?
