Unfolding against the backdrop of the booming, oil-rich city of Calgary is a showdown between two families, the wealthy McGregors and the debt-ridden Henrys. When David McGregor, the cutthroat CEO of an oil exploration company, decides his sprawling estate is not big enough for his family anymore, he sets his sights on Rivercross, a small but idyllic ranch left to the Henrys by David's father upon his death. But with sisters Lucy and Kate leading the charge, the Henrys won't go down without a fight, even if it means taking on an entire corporate empire.
