In a San Berdoo suburban housing development a woman is having trouble sleeping. Between a crying baby and snoring husband, will she ever get the rest she needs. Perhaps... eternal rest? She checks the baby monitor to see how serious the situation is, but is shocked when the camera on it (they have cameras on those now? Neat!) goes dark. It turns out power in the whole house is dead, and there's someone banging around downstairs!
The family then turns stupid, with the parents splitting up - mom hiding in the bathroom with the baby, and dad going to the older daughter's room to snag her cell phone (his is downstairs, where the thumping is coming from). Then, rather than just all heading to the bathroom to hide together, he leaves his 10-year-old daughter alone, hiding under the bed, with the responsibility to call 911 all on her while he goes off to check on his wife and other child. Even worse? He's had a gun the whole time! So why not just bring the whole family into the daughter's room and secure the door? Morons.
While the daughter is on the phone there are some screams and gunshots, then the killer enters the room, looking for another victim. Then the operator hears a gunshot and the phone goes dead. So yeah, parents? It's your fault that your whole family is dead because you couldn't be bothered to stay together and shove a dresser in front of a door.
Then, some time later, for reasons which confuse the hell out of me, we immediately cut to Derek running an FBI training exercise, letting the new people know that they're not taking their training seriously enough. Emily thinks he's being a little hard on the troops, but Derek thinks that toughness is what's going to save their lives out in the field!
Garcia then runs down the case details, and they're confusing as hell - this was the second home invasion in four days in which the entire family was killed, and the previous one happened just one block away! Wow, were those parents not vigilant enough if there had been a massacre that close just days earlier. Here's the confusing part - the killers broke in and cut the power and phone in both houses, but while one house had an old security system with bypassable wires, the other had a modern cell-based one, the service on which just happened to have to have gone into arrears, so the company wasn't listening for their signal. Of course, the killers must have known that, which is one heck of a lead.
Even more puzzling - at each house one of the criminals was killed, then the body left behind by his partner. The cops are assuming that the families killed one guy in a shootout in each case, but that seems like a hell of a coincidence - so the killer must be doing it, which means he also has to ensure that he's going into a house where the families have guns. That's a lot of research. How is he pulling this off? I'm guessing we'll find out after the opening credits!
