Operations believes Nikita is a threat to Section, and wants to kill her during a mission. She survives his plot, and when she returns to Section, she looks into the disappearance of Michael, and finds what she didn't expect.

Nikita has a new mission, to get David Henderson Williams, Vacek's associate. She also learns more about Michael's history with Elena & Simone. Elena offers Nikita to stay with her & Michael. Nikita accepts, but she doesn't feel too cozy after her thoughts & memories get the best of her. More problems come about as Vacek misses a meeting.

To flush out Vacek, Operations and Madeline order Michael to poison Elena, but Michael can't bring himself to do it. So Section poisons Elena anyway, while Michael is out on a mission, and her survival will depend on whether Vacek has enough conscience to visit his daughter in her time of need. Meanwhile, Section moves sleazy informant Mick Shtoppel in as Nikita's neighbor.

Michael is keeping track of Elena and Adam, and he becomes concerned when a new man enters their life. Sure enough, the man turns out to be a Secion One "Valentine Operative" by the name of Robert Corliss whom Operations has sent into to get Elena's Uncle, Stefan Vacek. It seems Uncle Stefan is taking over Elena's father's old terrorist business. Can Michael protect Elena and Adam once again without being exposed as still being alive? And can Corliss be trusted with Elena and Adam?
