Plot summary
Nikita and friends learn that Amanda and Tasarov have stolen a Helium-3 replicator prototype, a device that can produce a new energy source, in their bid to take over Zetrov. During their first failed attempt to intercept the replicator, Amanda wounds Nikita, but could not bring herself to kill her before escaping. Michael and Nikita follow Amanda to Zetrov's headquarters in Moscow in another attempt to retrieve the replicator. In the meantime Amanda leaves Sonya in charge (Lyndie Greenwood). Working with an inside man, Percy allows himself to be captured, and through an unwitting Birkhoff, convinces Division that Amanda is working with Gogol, and hence takes back control of Division.
Nikita takes the replicator, but is forced to seal herself in a containment vault when she is surrounded. Amanda drains the oxygen from the vault, but Nikita plays dead and escapes, but letting Amanda live. Zetrov fires Tasarov and appoints Alex their new chief executive officer, a position she passes on to friend Ilya Levkin. Without support, Amanda and Tasarov are on the run, but with a black box.
