Jen Galbraith is in love with Sgt. Tom Flaherty of the Royal Mounted. She is the daughter of Peter Galbraith, who is engaged in smuggling moonshine whiskey across the Canadian border. When she tries to warn her father and brother of the approaching police, she is arrested with the entire gang. Released on bail, her brother Val in an altercation shoots Snow Devil, a police spy; and trying to cross the border, he is caught in a blizzard. Flaherty is sent to intercept him but is drugged by the girl's father; Jen, however, braves the storm and delivers his dispatch. Flaherty later arrests Val on the murder charge, but the dying confession of his friend, Pierre, clears Val; and the lovers are happily reunited.
