As a joke, Lassiter sticks Shawn with a case where a man shows up naked at the police station claiming to have been abducted by aliens, but Shawn's investigation soon takes in him into an even stranger universe - speed dating.

SYNOPSIS: Vick wants Lassiter to take a case that he really doesn't want to. He looks up and sees Shawn and Gus putting on a psychic show for the other officers and gets an idea. He calls them over and says he's got a case for them. He hands Shawn the case file and tells him the victim is waiting to give a statement. As they walk into the interrogation room, they find a fully unclothed man, Fred Turk. With Lassiter happily watching through the one-way glass, Shawn and Gus proceed to give a very uncomfortable interview in which Turk claims he was abducted by aliens. As Turk tells them he woke up naked in a field with a headache, Shawn spots a faded ink mark on the guy's hand and chafe marks on the back of his heels.

The cops think Turk is a nutcase but Shawn knows the guy was dragged into that field. There was a crime committed here, he's just not sure what. Turk wasn't assaulted or robbed, but he was probably drugged with a hallucinogen. He also said he remembered a strong lavender scent and seeing barbed wire. Shawn knows exactly where that is.

When they get to the field, the police are already there - with another naked guy, Phillip Keiser. Shawn notices a tire pattern in the dirt, a broken strap off a woman's shoe and a spider web broken at a low level as if someone short had walked through it. Keiser says he doesn't remember anything and woke up with a headache, same as Turk. Shawn sees another partial ink mark on Keiser's hand and notices he has no tan lines anywhere on his body, same as Turk, which leads them to their next stop, the only tanning salon near where both the victims live that has the new "Insta-Tan" process, the only process capable of producing their flawless liquid tans. The attendant at the salon tells them that both Turk and Keiser were regulars and that it's always the single guys who keep up their tans. Shawn remembers the shoe strap and figures a woman might be targeting single guys at the salon, that is, until they run into Henry who tells them as an ex-cop and a regular at the salon, they are looking in the wrong place. Just then Shawn gets a call. There's been another victim, but this time he's dead.

Back in the field, Shawn spots a green smudge on a fence post. He also sees that the victim is pale - so much for the tanning salon theory. One thing the latest victim does have in common with Turk and Keiser is the partial ink stamp on his hand, all three of which, pieced together, form a four-leaf clover, giving Shawn his next lead. They head to Shenanigans Irish themed eatery, complete with green popcorn, and talk to Marvin, the host. Shawn sees the stamp, which matches the marks on all the victims' hands, and Marvin tells them it's only used for their events, like speed dating.
