Sarah Connor is having trouble sleeping. Which is funny, because if she had to sit through the monologue she gave at the start of this episode, she'd nod off within minutes. That rambling intro could match one of Mohinder Suresh's duller introductions in Heroes.
To get some rest, she checks into a sleep clinic. But, in the tradition of [[Terminator: The Sarah Connor Chronicles (TV Series)|Sarah Connor Chronicles]], she walks straight into a SkyNet experiment. The sleep center which is monitoring the sleep states of its patients is also surreptitiously recording brain data for some strange reason.
In between times, Sarah returns to the nightmares she's been experiencing. Except they play out in a linear pattern, giving a story within a story. Here Sarah confronts the man she shot in the desert factory a few weeks back.
