From a media release:

In a ferocious and unforgiving world of greed, deception, and harsh climates, the transatlantic battle to control the North American fur trade rages on as Discovery Canada’s original dramatic adventure series FRONTIER catapults into an action-filled third season with back-to-back episodes airing Fridays at 10 p.m. ET and 11 p.m. ET beginning Dec. 7.

Set in the late 18th century, with multiple plotlines unfolding from the offices of London to the Canadian wilderness, the drama is turned up higher than ever in FRONTIER’s new six-part season. Season 3 welcomes new players and new unlikely alliances who enter this merciless game in the pursuit for power and wealth – pushing each character to embrace new alliances or arm themselves against one another.

Seasons 1 and 2 of FRONTIER are now available to catch-up for free on Discovery.ca and the Discovery app. Following each television broadcast, episodes of FRONTIER are available for streaming on the Discovery app. All three seasons of the series will be streamed around the world via international broadcast partner Netflix.

FRONTIER’s talented ensemble cast is led by series star Jason Momoa (Aquaman, Justice League, GAME OF THRONES) alongside Landon Liboiron (HEMLOCK GROVE, DEGRASSI), Alun Armstrong (NEW TRICKS, Braveheart), Zoe Boyle (DOWNTON ABBEY, SONS OF ANARCHY), Jessica Matten (A Red Girl’s Reasoning), Allan Hawco (REPUBLIC OF DOYLE, CAUGHT), Michael Patric (ARROW, SUPERNATURAL), and Greg Bryk (THE HANDMAID’S TALE, WYNONNA EARP).

The consequences of the bold Black Wolf Company heist on Fort James have come with swift and vicious ferocity, and from the highest offices in London. FRONTIER Season 3 sees the agents of the Hudson’s Bay Company (HBC) violently cracking down on everyone, from Montréal to the wilderness, but the business of the Black Wolf couldn’t be further from Declan Harp’s (Momoa) mind. After Lord Benton (Armstrong) abducted Grace Emberly (Boyle) and set sail from James Bay, Harp set out on a treacherous rescue mission to get her back, which takes him far from the frontier.

After the successful heist of the HBC in Fort James, Michael Smyth (Liboiron) sets out to reassemble the Black Wolf Company – or what’s left of it. But the fallout is swift and furious, and the HBC crackdown has many feeling that Smyth’s head should end up on someone’s platter. Refusing to let his newfound infamy be his downfall, Smyth instead uses it as a sales pitch, stopping at nothing to seek out new alliances and build a team that can finally rival the might of the HBC. But when Smyth learns one of his new partners has a dark side business which challenges his humanity, it pushes him into a decision that could make all his risky work go up in flames.

Sokanon’s (Matten) break from the Black Wolf in the wake of Wahush’s death has her rejecting the trade in favour of protecting her people, especially Indigenous women who are being bought and sold around James Bay. As the ale house brothel in Fort James is a way station for some of them, Sokanon enlists the help of Mary (Breanne Hill) to outwit Imogen (Diana Bentley). But clever power player Imogen is always a half-step ahead, putting Sokanon and Mary in a terrifying battle for their lives.

In Montréal, a brutal shakedown by the HBC leaves the businesses of fierce competitors Samuel Grant (Shawn Doyle) and the Brown Brothers in shambles. Josephette DaCosta (Karen LeBlanc) fears that Douglas Brown’s (Hawco) emotions will run Carruthers & Co. into the ground and employs Malcolm (Patric) in a deception to try and save the company. The stress and anger forces Grant to leave the city for a time, leaving Cobbs Pond (Bryk), to keep the business intact, by any means necessary. While the men are away, Clenna Dolan (Lyla Porter Follows) connects with someone outside the confines of the Grant household in a risky relationship that could be her undoing.

FRONTIER is co-created by Rob Blackie and Peter Blackie, and produced by Take The Shot Productions and ASAP Entertainment, in association with Discovery, the exclusive Canadian broadcaster. Netflix is the international broadcast partner.
