Adam, Bree, Chase & Leo find out that Sebastian and two other former soldiers have started a bionic rebellion because Adam, Bree & Chase took out Krane who is the soldiers' father. As they threaten to eliminate anyone who stands in their way, the four heroes have to think fast or the consequences could be fatal.—ants0916
Only Perry's discovery of missing explosives foreshadows the bionic ex-soldier uprising brewing at the school. She becomes trapped with Donald as Sebastian finally springs his treachery, letting the Davenport kids watch as Donald and Perry slowly suffocate. Leo, having grossly abused his authority while having been temporarily put in charge of the students, finds his safety in jeopardy when the rebellion traps him alone in a room full of enraged bionic teenagers.—statmanjeff
