Terminator: The Sarah Connor Chronicles S2

Another malfunction causes Cameron to believe that she is actually a
human from the future named Allison. Sarah accompanies her pregnant
landlady to the hospital. Ellison continues to contemplate Catherine
Weaver's job offer.

A woman from Derek's past surprises him and elsewhere, Sarah, John and Cameron wonder what a T-1001 would need with a doctor.

Cromartie kidnaps Sarah and races to Mexico to find John. When Derek,
Cameron and Ellison discover what has happened, they come to their
defense--which leads to one final, deadly confrontation with Cromartie.

Sarah's quest to find the meaning behind the "three dots" leads to a
technology firm seeking an advanced microchip. Dr. Sherman is killed
while working with Catherine Weaver's A.I. computer, and Jesse comes
clean about her mission.

Terminators come after a family whose unborn daughter plays an
important role in the war against the Machines, and Sarah, Cameron, and
Derek try to protect them.

Sarah has visions of John's dead father as she tries to find a doctor
to remove a bullet from her leg, Jesse removes Riley from the hospital
after her suicide attempt, and Catherine covers her tracks after a
secret location is identified.

Sarah suspects that something fishy is going on at the medical clinic
where she is being treated for insomnia. During her stay, she has
flashbacks to a run-in she had with a man from the plant whom she
thought she had already killed.

As the Connors prepare to move, they find out that Riley is dead, and
Sarah begins to doubt Cameron's motives. Jesse flashes back to a
submarine mission in the future, and John Henry plays hide and seek
with Catherine Weaver's daughter.

Sarah and John hit the road without Cameron and Derek to stay with
Charley Dixon, where she reveals to Charey that her cancer may have
emerged. Meanwhile, a computer worm infects John Henry.
