While John continues to have more difficulty coming to terms with a
student who committed suicide and felt he was powerless to prevent it,
he becomes separated from Sarah and Cameron while they're searching for
some stolen cargo when he's accidentally trapped in the back of an
armored truck loaded with enough metal to build 500 endoskeletons. But
instead, John finds another Terminator with an unknown mission.
Meanwhile, the murder of a plastic surgeon that Agent Ellison is
investigating leads him to a surprising suspect, while Cromartie, the
terminator who followed Sarah, John, and Cameron into the future,
continues to rebuild his bio image into another person.
