Spirited Lady Charlotte Bellamy wants adventure and she gets it when she disguises herself as Charlie Bell and manages to land a job as a jillaroo with a mustering team on Sundown - a huge cattle property on the Queensland- Northern Territory border. Charlie is sure she's ready for the challenge, but what she doesn't bargain for is the appeal of the outback hero - Sundown's gorgeous owner, Matt Lockhart.

Duty sends her back to England and a marriage of convenience, but her heart still longs for Matt.
