Synopsis

Steed’s colleague, Sean Mortimer, arrives in a state of profound disorientation. He suspects a traitor within their organization, yet a drug has robbed him of most memories, leaving him adrift in a fog of confusion. As Mrs. Peel begins her own inquiry, she too succumbs to the drug's effects, and both she and Sean are abducted by bikers. The responsibility for averting disaster falls to trainee agent 69, Tara King, whom the spymaster known as ‘Mother’ introduces to Steed as his only hope.
