Hardworking Hayley is plunged out of her depth when she hands over control of her big day to a man with a crazy underwater plan. Her fiancé Ian has just three weeks and £12,000 to pull off the wedding of a lifetime. Working as a sports physio, Hayley dreams of hanging up her tracksuit and becoming a gypsy princess, but hopeless romantic Ian wants to throw her in at the deep end of their local leisure centre, ruining not only her dreams but also her hair, make-up and dress. Will Ian's wet wedding make a big splash or will he end up high and dry?
