Picking up five years after the passing of his boss, Vito Rizzuto, Declan Gardiner has climbed to the top of the Montreal drug business by removing his rivals and setting up a deal with a Mexican cartel.

After Teressa and Christian steal Declan's cartel shipment, he must forge an alliance with Alex LaChance, head of the Devil's Kings biker gang to get it back before his five million dollars payment is due.

Families don't get touched. At least that used to be the rule. But when the other side breaks it, Declan reciprocates by shattering it completely.

Nats and Valentina each deal with the consequences of their actions. Declan's smooth pathway through the ports hits a major snag.

Teresa and Christian's burgeoning fentanyl business causes major collateral damage for Rose. Valentina's confession comes back to haunt her.

As word of Valentina's dilemma spreads, tension within the Cosoleto family grows. Teresa and Christian try a new tactic to undermine Declan.

Declan ratchets up the heat on the Cosoletos and continues to pursue Teresa and Christian. The gift Declan promised is delivered to Nellie.

As the bikers make trouble for the Cosoletos, Nellie's deal with a key witness hits a setback. Indiscretions in his own camp come back to bite Declan.
