Jerry's going to spend the whole wedding trying to sabotage it so he can get a date with the bride. George will be trying to sabotage it because someone made a weird face about the price of the cake. Kramer will earnestly try to help it go right, only to alienate every single one of the providers, and then he'll get his own providers which will mean the fish option's still squirming "that means it's fresh, Jerry! Fresh!". And it will turn out Elaine had a thing with the groom which went horribly wrong, and a thing with the priest before he was a priest, which will lead to him abandoning priesthood a couple of hours before the wedding, thinking he still has a chance with her.  

In the aftermath, Jerry's date with the bride goes downhill when he discovers she believes in waiting for marriage before having sex. George ends up having to pay for the cake out of his own pocket, and then can't understand why the former groom's parents just won't agree to buy it from him. Kramer starts his own wedding planning business, which leads to an even larger disaster at another wedding where everybody gets food poisoning, since he was trying to use the same fish "it wasn't squirming anymore, Jerry!" Elaine feels like she has to go out with the former priest, only to have the guy be constantly wrecked by guilt the whole time, then he tries to convince Elaine to be celibate together.
