Follow the lives of four men on the outside of the law in 1860's outback Australia, as they come up against authority, the rich and greedy, and the weaknesses of their own hearts. After a month away from Hopetoun, Jack and Dan return home to find new Superintendent of Police, Fuller, arriving, causing their existence as bushrangers to come under threat. Jack rekindles his romance with pub owner, Mary, but any hope for a future with her is snuffed out when Fuller captures the Wild Boys.

Jack awakes after being shot, to find a shocking discovery at the Ryan farm. Cared for by Mary, he's almost caught when Fuller raids her pub. But when Jack learns that Joey Butler was behind the shooting at the farm, he sets off for revenge, ruining Mary's plan for a new life.

Mary's bar is burnt down as a result of foul play, and Jack decides to rob the Hopetoun Bank to try to help her.

With the Hopetoun Cup being run in town, Jack is determined to ride and win the event - and make a nice score by stealing the favourite, painting it up and entering it as their own. With Frank Butler in town to look for the killer of his brother, Fuller determined to fill his jail with criminals and a dangerous detective hired by the bank to find the culprits, the boys are in the midst of a very deadly enterprise. But Scanlon is riding in the race, and Jack is going to do anything it takes to stop him winning.

Dan's past comes back to haunt him when an old girlfriend convinces him to marry her — the gun pointed at his head is very convincing. The Wild Boys are also being threatened by a new bushranger in town, Captain Moonlite, who's dangerous, eccentric and rather elusive. Emilia's new suitor, Rupert Wentworth, chosen by her father, turns out to be more charming than Emilia imagined, if not a little flamboyant. Meanwhile, in an effort to protect Tommy, Jack puts his life on the line at the miner's court.
