Alias

Sydney, Vaughn, Jack and Dixon are stunned by CIA Director Hayden Chase's choice to be their new boss. Meanwhile, Sydney and Vaughn's possible reconciliation is in doubt and Sydney learns an appalling secret about Jack that threatens to destroy their relationship. Additionally, against Sydney's vehement objections, her new boss partners her with Jack to hunt down a modern-day samurai; Sydney's half-sister, Nadia, is reluctant to return to the spy game since learning the truth about her father. Vaughn and Jack share a surprising bond over Jack's unspeakable past misdeed - much to Sydney's chagrin.
