Season 4 - Episode Guide

Something is differs about Nikita. Has section's mind-control scheme removed her ability to form emotional attachments? Michael has suspicions... and becomes a marked man as he scrambles for answers.

Kill Michael! But bringing the elite agent down is easier said than done as he closes in on a stunning secret: Section's creator, a foe of Operations long presumed dead, is alive and held in cryo-containment.

Gambling that Michael will not attempt to kill Nikita, Operations send her and a team of lookalikes to terminate him. But the ruse fails and Michael is able to broker a deal that reinstates him inside Section.

Michael's again part of Section... and racing the clock to counter-program the damage done to Nikita. Birkoff provides cover so Michael can be alone with her and a treatment seems to work. Or does it?

Married to the job. And to the enemy. Posing as drug dealers, Nikita and Michael cozy up to a weapons dealer who, smitten with Nikita, proposes marriage. Operations' order to his femme agent is clear; accept!

Nikita has her secrets. As it turns out, so does Helmut Volker. He's not who he appears to be - he's actually a knowing player in this bullet - and subterfuge-filled espionage world of Mr. and (near) Mrs.

Operations mixes personal feelings with power when he assigns Michael and Nikita to assist a man who presumably helped the Section One leader in Vietnam. Birkoff finds he has a twin brother on the outside.

Nikita is mysteriously released from Section and receives an even more cryptic order: Kill Operations. Complicating the order is its source... and the revelation of Operations' secret family ties to Nikita.

After a bio-breach, Oversight sends a Bio-Med team to scan for viral contamination - a process that in reality steals agents' memories/expertise for future uploads into recruits who will become perfect agents.

Oversight provides an agent to assist Operation's hunt for a missing Command Clone Program: an agent with telekinetic and clairvoyant powers and the emotional control of a child... because he is a child.

Michael and Nikita are put in charge of the accelerated training of raw, attitude-filled recruits, only to discover that the newbies - along with Michael and Nikita - are to be sent on a suicide mission.

"A woman in love may prove to be a more formidable opponent that the one she loves," Michael says. And that's especially true when Madeline falls for a high-level Red Cell captive. Birkoff faces his brother.

A Section operative is detached, methodical, professional, impersonal... except where family is involved. Michael learns a Valentine op is romancing his wife Elena and that she's a target of a terrorist group.

Either he's right, or they're all dead wrong. Birkoff pinpoints the location of Red Cell's elusive Cardinal. But a failed attempt to retrieve the rival leader angers Oversight and puts Section One's existence in peril.

An A.I system Birkoff develops turns renegade, endangering the lives of personnel and protecting itself from shutdown. Only Birkoff can defeat the rogue machine. But the attempt may cost him his life.

Welcome, y'all. Posing as geologists Michael and Nikita enter a tiny, backroads Tennessee town to hunt for a downed ComSat Alpha satellite. Birkoff's twin brother awakens to find he has been 'recruited'.

The investigation into the activation of the facility's self-destruct codes leads to a lone hacker... and gives Operations a chance to play the geek's 'war game' for keeps against Red Cell. Jason begins training.

A deranged junk collector adds something new to his collection: Nikita. he finds the injured operative after a failed mission, restores her to health and holds her captive in chains. Object: matrimony!

Operation Madness. Section gives Nikita a psychosis-inducing drug so that she can be admitted to a psychiatric ward for a mission. But the institute's meds and therapies may be more than she can overcome.

Has Nikita turned? She cooperated with Red Cell, imperils Michael and undergoes a process to give her a new face. Meanwhile, Section ratchets up the pressure on Jason to assure he becomes Birkoff's double.

She looks and sounds like com expert Quinn. But she isn't Quinn... and she has a profound influence on Michael. Plus: Jason wraps his mission. Isn't it just like Section to reveal there's now another?

Nikita and Michael's absence causes a leadership void in Section, yet that doesn't stop Operations from deciding to cancel one of them when apprehended. But a wild card interferes: the mysterious Mr. Jones and his even more unexpected accomplice.
