Another incursion takes place in Section One, this time in the form of a virus that is making Section One's members sick, one by one. Taking matters into his own hands, George orders in his own Bio Team to treat Section's members. Operations suspects George has an ulterior motive. Sure enough, when Section's people, starting with Walter, followed by Nikita, go in for their ""examination"" with George's Bio Team, they come out vegetables. It seems George's team is mind wiping (downloading the contents of the brains) the Section's members. This process causes them to relive their lives, before leaving them vegetables. Can Michael and Birkoff stop George's team before everyone in Section One gets their brain sucked?
