The initial excitement over Donald and Douglas's bionic upgrade wanes when they discover that it can't apply to Bree, Chase or Adam (as their bionics stem from earlier technology). Only Adam can face their projected obsolescence with ease. Meanwhile, following a run-in with the law, Daniel joins the academy as its newest student, with Leo as his appointed mentor. While training, several students notably vanish. Soon all the former ex-soldiers (plus Daniel) are gone. An emergency message soon solves the mystery: Giselle has returned to destroy them all.
