[1] Grace, lying to her father that she is saying goodbye to the gang, sets off to Liv's place to prepare for her wedding.
Alo, Rich's best man, has not brought a proper map with him, and drives them into the middle of nowhere, where the van breaks down.
Mini, meanwhile, gets fed up with Alo and Nick's seemingly uncaring behaviour, because she is worried that something will happen to her friend.
Problems get worse when Professor Blood, while having lunch, sees Grace's location on his GPS and immediately goes after her.
Seeing him hastily button up his trousers, they realise what has happened and, frightened that Franky might hurt herself in her current state of mind, join in the chase.
As they catch up with Franky and call to her, she is distracted, trips over a branch, and falls over the side of a cliff.
Meanwhile, Alo and Nick see David Blood drive past on his way to the church, and desperately flag down a ride.
But Grace and Rich decide that they don't need to get married after all, and proceed to a nearby marquee, to celebrate the wedding.
