However, risk-taker Simon decides to gamble his future happiness and ultimately his relationship on a wedding 5,000 miles away in Las Vegas. Will the bright lights blind him to what his bride Kaleigh really wants? Will it be the biggest mistake of his life? And will he even have a bride to marry on the big day?
