The gang are just about to close a deal worth 50,000; that is, until Sean is distracted by someone with whom he has a score to settle. He lets the mark walk off with the money while he pursues this man. Emma is shocked to discover that the man is none other than Rex Kennedy, Sean and Emma's dad, who walked out on them 25 years ago.

Sean is determined to get even, and wants to lead a con on his dad to get the money he owes in back-dated child support. The gang are dubious but Sean is adamant he wants to go through with it, so they reluctantly agree.

Rex is a property developer, so Sean decides to run a version of the 'treasure map' con. Mickey poses as a surveyor interested in buying Rex's land, and while visiting the site they spot Sean, a treasure hunter with a metal detector who finds, and then hides, a jewel encrusted bracelet in the mud. When Rex spots this he visits the site later to take it for himself.

Sean tracks Rex down and spins him a yarn about a group of aristocrats in the war who used his Uncle Lonnie to smuggle valuables to America. Unfortunately the plane was shot down and the jewels were buried with it, and he thinks that Rex's land is where X marks the spot.

Sean and Rex go to a retirement home to visit Albert, posing as Lonnie in order to find out clues as to where the treasure could be buried. Sean is shocked that Rex is honest and decides that he wants out. But Rex is having none of it - he won't let Sean walk away when the treasure is worth millions.

With no plan B in place, Sean is out of his depth. Will he and Emma get to even the score with their father and find the answers they have been looking for? Show less
