Prepare for the invasion.

According to CSI Files sources, "The Theory of Everything" opens in the police department. The Desk Sergeant is ignoring the woman standing in reception: Evelyn Polychronopolous. Evelyn is wearing a tinfoil suit and matching hat, but the Desk Sergeant is clearly used to the sight. She's a regular, and she's currently talking about strings connecting time and space and an invasion that will happen that night. Her tinfoil suit will protect her, she believes.

Nick walks in, carrying his kit. He waves to Evelyn and says hello--clearly, he's used to seeing her as well. As he walks toward an interrogation room, Evelyn calls after him, warning that the invasion is coming. Nick smiles and continues on his way. He steps into the interrogation room and sees Brass sitting across from Kyle Planck, a drunk man in a flannel shirt.

Brass is showing Kyle crime scene photos, but Kyle doesn't want to look. Brass tells him that he killed 'her' and then dressed her before tossing her into his truck. A trooper caught him putting the body in the pick-up, and Brass tells him they're going to find out what else he did because the body is in autopsy. Nick pulls out an Intoxilyzer.

Meanwhile, in the coroner's office, David Phillips is removing a blood-stained dress from their victim, his expression troubled. Doc Robbins walks in and asks if this is their 'Jane Doe'. The 'her' they are dealing with is literally a doe, and Doc Robbins can't help making a deer joke and taking a picture for his scrapbook. David tells him this is animal abuse.

Doc Robbins tells David to help him remove the arrow, and when they pull it from the deer's body, they see that it isn't actually an arrow. Instead, it's a bolt from a crossbow. Back in the interrogation room, Nick is trying to get Kyle to use the Intoxilyzer. Kyle is denying that he killed the deer and instead insists he found her like that--and he didn't dress her up, either. He was taking her to the vet, he says. Nick points out that a crossbow was found in his truck.

Kyle asks if they can give him a break. He just got divorced and his ex-wife took everything. Brass brushes that off, and Nick tells him to blow into the Intoxilyzer. Kyle bolts, darting out the door and elbowing the officer stationed outside in the nose. He continues to run down the hall, knocking down officers and civilians alike as he heads for the exit. Brass yells for them to stop Kyle, and Officer Casella pulls out a can of pepper spray and hits him in the face with a stream of red liquid.

Kyle shoves past Officer Casella and knocks Evelyn aside. When it looks as though he might make it out, a group of uniformed officers charges forward. Officer Choi is in the lead, and Brass gives him the order to take Kyle down. Choi pulls out his taser and aims--as the electric prods shoot out of the taser and hit Kyle's flannel shirt, the man bursts into flames. Officers grab fire extinguishers as Kyle is engulfed, and Evelyn calls out to Officer Casella, asking if he believes her about the invasion now, and then she disappears out the door.

The team has to figure out how Kyle Planck mysteriously burst into flames, and they wind up dealing with even more unusual deaths. A billboard truck driver is heading down the road at night when he is blinded by a flash of light that appears without warning in front of him. When he gets out to see what he ran over with his truck, he discovers the body of Evelyn Polychronopolous in the road. She is dead, still in her tinfoil suit. Mandy, Henry, Wendy and Archie are all back to help deal with the case load when several more bodies and some mysterious green blood turn up, proving that abnormal is the norm in Las Vegas.
