Nikita

In the fourth season premiere, Nikita is still on the run after she was framed for the assassination of the President of the United States. A reporter from the news channel ENN named Dale (recurring guest star TODD GRINNELL -- Revenge, Desperate Housewives) starts questioning what really happened that night and Nikita sees this as an opportunity to clear her name. She re-enters the country to talk to Dale but walks right into a trap set by Amanda. The team is alerted and Michael sets out to find Nikita before Amanda does. While Birkhoff and Ryan help Michael from their new mobile office — a high-tech aircraft — Alex stakes out a human-trafficking ring and learns the Shop is involved. Things go south and Alex is surprised when Owen/Sam shows up at the scene. Recurring guest stars include LYNDIE GREENWOOD (Sleepy Hollow) as Sonya and DAVID S. LEE (The Nine Lives of Chloe King) as Mr. Jones.

Nikita reunites with Michael, Birkhoff and Ryan aboard the team's aircraft command center. Michael refuses to discuss their relationship but tells Nikita she should stay with the group and let them help her clear her name. Ryan realizes Amanda is making doubles of VIPs with the Shop's help. Nikita discovers that one of the doubles is the director of the FBI (guest star ALEX CARTER -- CSI: Crime Scene Investigation, Burn Notice), but doesn't know how to kill him without exposing herself. Meanwhile, Alex holds Sam at gunpoint and demands he return what he stole from her, but when a gang of thugs attacks them they are forced to work together to escape.

Tensions continue to escalate between the United States and Pakistan after Amanda plants evidence that Pakistan hired Nikita to kill the President. Ryan becomes suspicious of Birkhoff's increasingly odd behavior and tells Nikita and Michael that he thinks Amanda may have kidnapped Birkhoff and planted a double on the plane. An NSA official, Ronald Peller (recurring guest star JUDD NELSON -- The Breakfast Club, St. Elmo's Fire, Billionaire Boys Club, Suddenly Susan), gets under Birkhoff's skin. Meanwhile, the CIA captures Alex and questions her about her involvement with Nikita.

Jones (recurring guest star DAVID S. LEE) benches Amanda and takes back the reigns of the operation. He calls Nikita and offers her and the entire team complete freedom by wiping away their identities and faking their deaths if they walk away from their mission. The team lands the plane on a secluded Pakistan air strip, but when the local drug czar and his men storm the plane and demand 10 million dollars, Nikita calls Alex for the money. After Alex pulls diamonds out of a safe deposit box to pay the insurgents, Sam sees an opportunity to recoup his losses and contemplates stealing the diamonds. Meanwhile, Michael comes face to face with an old adversary, Ramon (recurring guest star SIMON KASSIANIDES -- Quantum of Solace), who hits Michael with some hard truths.

Just as Nikita is finally starting to see an end to the long war with the Shop, Ryan confesses a secret that could unravel it all. Meanwhile, Michael tries to get Nikita to accept their new circumstances as he contemplates what comes next for the two of them. Realizing Sam was planning to steal her diamonds, Alex gives him a suitcase of fake diamonds to deliver to her contact in France. Alex is surprised when he upholds his end of the bargain and doesn't take off with the jewels. However, things get messy when Sam is jumped by the loan shark he owes money to and Alex must step in to save him.

In the series finale, frustrated that MDK is still active, Nikita decides to end it her way. Leaving Michael and the team behind, Nikita takes Alex on the road to exact revenge. Nikita and Alex capture Jones (recurring guest star DAVID S. LEE) and force him to reveal the names of the rest of the members of MDK. Armed with the information, Nikita goes down a dark path that may ultimately cost her soul. Michael tracks her down and must get her to surrender before the military opens fire and kills her. However, Nikita isn't one to give up on a fight, leading her to make a shocking decision.
