Ash and Grant got themselves into a whole load of magical trouble when they accidentally set fire to Merlin's office and destroyed many items of historical significance. Merlin tasked them to go back in time and retrieve each of the artifacts they destroyed. This time out, they've got their work cut out for them when Merlin sends them back to 1899, at the tail end of the wild, wild West. Their mission is to find none other than the infamous outlaw Butch Cassidy, and somehow get their hands on something near and dear to Butch's heart - his Colt .45.To do this, they must become outlaws themselves, and join up with Butch's gang, the Wild Ones. They swiftly find out the real wild and woolly west is more stinky and dangerous than it is on any television show they'd ever seen. Not even Ash and Grant are sure they can pull off living on the wrong side of the law, especially during a time when justice was often served with a bullet, and the life expectancy for outlaws was notoriously short.
