In April 1929, in prohibition-era Nova Scotia, Duska Doucette, Larkin Wade, and Jolene Taylor, suffer tragedies.

Facing destitution, they make the difficult decision to become rum-runners.

Pretending to fish for lobster, the women transport contraband liquor from ship to shore. But their work is fraught with frightening encounters with RCMP patrol boats, the Coast Guard, and rival criminals. They're also harassed by angry fishermen who believe women have no place on the sea. Then there's Constable Asher Hayes, suspicious of the women and tracking them closely.

When disaster strikes, the women must face an even deadlier foe-and fight desperately to make it out alive.
