Ever wish you could have a mulligan for your wedding day and do the ceremony over again? "I Do Over" gives couples a second chance at their wedding. Renowned wedding and event planner Diann Valentine plans a second wedding ceremony for couples who had a disastrous walk down the aisle the first time around. Diann transforms bad bridal memories -- plagued by natural disasters, fainting grooms and missing dresses -- into dream ceremonies that try to wipe away the memories of the disastrous first ceremonies. Diann and her team have just five days to pull everything together for each ceremony, with designer wedding dresses, whimsical cake designs and breathtaking venues.
