EastEnders airs possible danger next week, as Callum Highway and Ben Mitchell's wedding day arrives.
Callum is in a panic when his partner Ben goes AWOL, after the police officer confessed all on his undercover operation against his dad Phil Mitchell.
But this is the least of his worries, when Phil soon finds out the truth - and he's full of rage.
Callum's brother Stuart accidentally lets slip that Callum was working undercover against Walford hard man Phil.
Meanwhile, Callum is waiting at the altar for his husband-to-be, unsure if he's going to show up.
Phil knows something is wrong with Ben, as his mother Kathy fears he'll leave his partner at the alter and asks him to have a word.
Ben doesn't tell Phil why he and Callum have hit the rocks, and on the day itself he suddenly goes missing.
It's then, after Ben refuses to help Phil get to the bottom of everything, that he bumps into Stuart who is also in search of Ben.
Stuart suddenly lets slip what happened with Callum, and why he and Ben have fallen out, unintentionally confirming what Callum did with work.
Phil is left with a deep rage, but will he take revenge?
Callum is certainly in danger as Phil is not to be messed with - after all, family is family.
The betrayal, that could have seen Phil sent to prison for the rest of his days, is bound to have major repercussions for the family.
But who will Ben side with - the father he's always battled to be good enough for, or the love of his life?
Will they even make it down the aisle in what is meant to be the wedding of the year, especially where Ballum fans are concerned?
Viewers will have to stay tuned to watch the scenes unfold, with much more to come.
EastEnders airs Mondays and Fridays at 8pm, and Tuesdays and Thursdays at 7:30pm on BBC One.
