The Chairman is killed in his home, and when the Spies go to find Cross at his home they find him unconscious, covered in blood, with the knife nearby and money transferred into his account. Cross is quickly put into prison and replaced, and the Spies decide to investigate the frame job. While thwarting a plan to steal nerve gas and ducking an internal investigator with the support of their new boss Erica Pierce, the Spies gather evidence but when D.D. and Shane get back they're arrested for stealing the nerve gas – Erica framed them so she could take and steal the nerve gas and has them sent to prison.
Cassie is still out on her own and figures out how Cross was framed, and with Duncan's help gets into prison and gets Cross out while D.D. and Shane escape on their own. Erica flees and the Spies and Cross track down and capture Erica. The Chairman reveals he's alive and faked his death to flush out the killer
