Mary's thrilled to have her younger brother Ben come to town. He's fun, charming and a great uncle to Tommy. But Ben has other reasons for coming to Hopetoun, and they don't involve family. He enlists the help of the Wild Boys in what appears to be a straight-up cash robbery. Except it's not - they find themselves holding up the Rope Gang, a seriously nasty group of bushrangers, and nothing goes to plan. Shortly after, Tommy is kidnapped and a ransom demanded. But even once Mary scrabbles the money together, with substantial help from Fife, Tommy is not handed over. The hunt for Tommy is is on - led by Fuller, Scanlon at Mary's side. The Wild Boys conduct their own investigation as Jack becomes obsessed with finding Tommy and returning him safely to Mary. (thetvdb.com)
