Sean Mercado, a rookie Dallas Marshal, and Nicholas Fournier, a Canadian cop, are pulled into Jubilee and Kieran's lives after a near death experience for Jubilee who is shot during a bank holdup that leaves him seriously wounded. Former Canadian Special Ops Nicholas Fournier never dreamed making a deposit at a Dallas bank for his ailing aunt would change his life, but it does. He meets US Marshal Jubilee Mason who in turn introduces him to Sean Mercado, a new recruit to the Big D. Nicholas is still reeling from a romantic fiasco where he threw caution to the wind traveling to Texas to meet a guy he communicated with online. Though planning to fly back home, he's tempted to spend a little more time with the hunky Louisiana transplant and find out a little more about the US Marshals. He soon finds there's a lot going on in this hectic Texas city and it ain't just summer rain.
