Having woken up in Hong Kong, with no memory for the last two years (!), Sydney returns to Los Angeles to try to piece together the last two years of her life and discovers the fates of her friends and family: Vaughn has married thinking that Sydney was long dead; Marshall is having a baby with CIA tech expert Carrie Bowman; and Dixon is now the new division head of the L.A. office branch of the CIA. Sydney also learns the shocking fates of Jack and Sloane; the former is in CIA custody for communicating with Irina whom still is in hiding, while the latter is living in Switzerland under house arrest in exchange for co-operation with the CIA. Sydney is granted temporary CIA clearance on a case that may help her regain her memory and she meets a new enemy group called The Covenant.众人鄂然，没想到这个进化者想出的主意竟然让鼠山大帝用在他身上了，这算害人终害已吗，鼠山大帝也太凶残了些。不过想到他用活人涮火锅，为了逃命这点罪过似乎也不过分，只是在被带走前他还是垂头丧气，说话也比在山庄的时候缓合了许多，为何出去一会儿就变成这样了。
