Karis joins forces with her cousin Jackson to take down Raven, a genius vigilante targeting Jackson's unit.

SYNOPSIS:

In this epic conclusion to the KNOCKOUT franchise, Captain Jackson Peterson has finally found a semblance of peace after coming to terms with the loss of his wife Jenette and saving his son Hunter after extracting the cure for cancer. However, that peace is shattered when a series of coordinated attacks threaten his cousin Karis and her newfound family: her wife Eris, their girlfriend Lena, and their adopted son Jayden. The orchestrator of these attacks is a shadowy figure known only as Raven, who harbors a deep-seated vendetta against Jackson for the death of her sister during a mission gone wrong in his unit. As Jackson grapples with the weight of his past choices, his world spirals into chaos when his girlfriend, Lt. Alicia Jones, is critically injured in one of Raven's ruthless strikes. Driven by love and vengeance, Jackson teams up with Karis, who has embraced her dual life as the lethal assassin known as 'Knockout.' Together, they unite with Karis's resourceful wife, Eris—who originally took on her temporary identity as a ruthless assassin known as Rosa—and Lena, a former thug with her own ties to the criminal underworld, known as Viper, to take down Raven and gain their hard-earned peace back.
