Matt and Kathleen's wedding day is marked, and could be marred, by a woman who appears at the church and wants to buy a horse from Matt. Matt finds a riderless horse and goes off to investigate, without telling anyone.

Montana's new horse is stolen by rustler Seb Holgate after she bests him in a shooting competition. Montana sets out after him and is joined by Kathleen.

Montana and Rob find an American surveyer who has been shot. They help him and he reveals he was shot by a man spying on Montana. When Montana claims that she has seen someone loitering by her property and her horses are poisoned, Rob is determined to protect the woman he has more than neighbourly feelings for.

Montana is charged with the murder of Sam Taylor's father and scheduled to be extradited to America. But Matt and Kathleen get her a hearing in Paterson's Ridge with Matt as her defender.
