Ginger Snaps Back: The Beginning is the prequel to Ginger Snaps and Ginger Snaps 2: Unleashed. The final part of the Ginger Snaps trilogy takes place in 19th century Canada, following the exploits of the antecedents of the Fitzgerald sisters of the two previous movies: Ginger (Katharine Isabelle) and Brigitte (Emily Perkins), who are identical to their modern-day counterparts in all respects.
Fort Bailey, a trading fort in the western Canadian wilderness. Each spring a party of thirty six men from the fort travelled to Hudson's Bay in boats laden with pelts. The men returned in Autumn with provisions to see the fort through the harsh winter. In 1815 the party never returned. With the men two months overdue, the freshly orphaned Fitzgerald sisters (their parents having drowned), stranded in the wilderness, are brought to the fort by a resident Indian Hunter. The men there are suspicious of them, but, reluctantly, the sisters are permitted to stay.
Almost two hundred years before the attack on Ginger at Bailey Downs in Ginger Snaps, orphaned sisters Brigitte and Ginger find themselves lost in the cold Canadian wilderness. The sisters encounter an Indian Seer who warns them of impending danger, one that would ultimately end in the death of one of them at the hands of the other unless they 'kill the boy'. The horse they are travelling by bolts, and, chasing the horse, Brigitte is caught in a trap set by an Indian hunter. The hunter arrives, and releases her, then leads the sisters silently to Fort Bailey, a trading fort of the Northern Legion, where they take refuge.
