Scene on youtube - robot pets cat to death...
Gideon Banks, an electronic engineer, twenty years ago lost his wife
Liz and son Simon in a horrific car crash. At that period of time he
was working at the so-called Neural Archiving Project — NAP for short.
This technology was developed to create smart computers by
transferring human engrams into computers.
The company eventually gave up on the technology, but Gideon didn't.
After years of quietly perfecting it, he built at home a small robot,
using parts he stole from Concorde Robotics, where he now works. Zoe,
Gideon's niece, discovers Gideon's secret, that the robot contains
actual neural engrams from Gideon's dead son Simon, which Gideon has
integrated into the robot in hopes of re-creating his son. And now,
the robot actually has memories of the real Simon.
Zoe becomes worried not only about Gideon but also about the robot
that sounds and acts a lot like her little cousin used to. And she
begins to realize that Simon may not have been the lovable little
angel that everyone believed he was.
"Simon" becomes more and more demanding, putting pressure on Gideon,
who could lose his job. When he asks Zoe to "babysit," the robot
attacks during a tantrum and injures her. When Gideon returns they
argue about "Simon" being a robot or as Gideon insists, a true boy.
Zoe leaves upset. Later, Gideon apologizes over the phone and asks her
to look after Simon again as he has to work. Zoe does so, but this
time gets along much better with "Simon" who also apologizes for
Gideon's boss finds out about the robot, and claims that since it was
built from company equipment, it belongs to the company. When he tries
to forcibly take "Simon" away, Gideon becomes enraged and clubs the
man on the head, killing him. Gideon and Zoe begin to argue, but
"Simon", who becomes distraught at recognizing the seriousness of the
situation, shouts for them to stop and claims that he is ultimately
the one at fault. Upset, "Simon" confesses that "he" was responsible
for the car crash: when Liz refused to take Simon to the toy store,
Simon threw a temper tantrum and grabbed the steering wheel, causing
the fatal crash. To him, that unwise tantrum was the first domino to
start the chain reaction that has now led to this moment.
Realizing what he's done could seriously impact Zoe, Gideon ushers her
out, assuring her that he'll remedy the situation and do the right
thing without affecting her. Soon afterwards, Zoe hears a gunshot and
rushes back in, only to discover that Gideon has copied his own mind
into another robot before committing suicide. Zoe can only look on in
horrified silence as the two robots chat like father and son.
