The story of Harry Walford, an unlikely hero who overcomes hardship, emerges triumphant, and, in the process, pioneers the overland stock route from Southern Queensland to Adelaide. Based loosely on a true story, Bullseye takes place in Australia around the middle of the nineteenth century. Walford is a disgruntled stationhand who has found a ray of happiness in his relationship with maidservant Lily Boyd. However, when Lily comes into an inheritance, she breaks off their romance, causing Harry to turn to cattle-duffing (rustling). Arriving safely in Adelaide with his stolen cattle, he discovers that Lily is also in town but has lost all her money and been reduced to working in the local bordello. Rather than gloat, he decides to rescue her.
