FBI headquarters. Mulder is interviewing someone when Scully walks in. The man turns -- it's Gilmore, with a new, rough-hewn mouth, courtesy of surgeons. He blames Anson for his troubles.

Mulder and Scully go to Anson's trailer-park house and find it has a large boat parked in the driveway. Anson and his wheelchair-bound brother Leslie see the agents approach and worry they're from the IRS. The mysterious rug woman is hanging around too.

The agents get little information and so head for the storage facility. Scully notes that the furniture in unit 407 includes valuable antiques; she suspects theft, but Mulder notes that no amount of larceny can explain the missing mouth.

He has one wish left. He tells the unimpressed woman he wants to become invisible at will. Done -- but he has to take off his clothing because he didn’t specify that they become invisible too. He then goes running across the street toward where two attractive woman are fixing a bike, and promptly gets hit by a truck.

Later, there's a body-shaped impression in the dirt by the side of the road. A bicyclist trips over him.

The hospital. Some disconcerted doctors wheel in a gurney and leave it with Scully. She starts brushing yellow powder over the sheets, revealing the contours of a human body. She smirks, apparently enjoying herself.

The powdered body is now visible, as is Mulder. Scully exults that this case will redefine the "boundaries of science." Mulder, meanwhile, has researched a photo of the mystery woman and some guy who apparently died of an "extreme priapic condition."

Trailer park. The boat has graffiti on it. Mulder talks to Leslie about the mythology of genies. Leslie hums music from an old TV show, but then gives Mulder a bottle, supposedly where the genie came from.

Back at the storage area, Leslie goes to get the rug. He misunderstands the genie's implication that he fix his injury, only wanting his brother back instead.

Mulder does photo research. Finds the mystery woman in pictures with Mussolini and Nixon.

A team arrive from Harvard Medical School to view the invisible body. To Scully's embarrassment, it’s gone.

Anson is at Leslie's house, sitting at the breakfast table while flies buzz around. He looks like a zombie or corpse.

Leslie is upset at how badly his wish that his brother return turned out, so makes a second wish that Anson can talk. Jenn the genie tries to dissuade him, but finally relents. Anson emits an awful, protracted scream.

Meanwhile, Mulder explains to Scully that the disappearance of Anson's body must be the result of a wish.

Back at Leslie's. The screaming finally ends. Anson complains he's yellow and cold. He starts lighting matches around the stove. Leslie says he wants to use his last wish on himself.

At last, explanations

Mulder and Scully drive up, and walk toward the house. It explodes. They fall to the ground, and the rolled-up rug falls nearby.

Soon afterward, Mulder interrogates Jenn. She removes her sunglasses and reveals the "mark of the Jinn," a sort of jewel-like thing near her eye.

As she reveals, she's 500 years old or so and used to be human, living in medieval France when an old Moor came by and granted her three wishes. She chose (1) a stouthearted mule, (2) a magic bag full of turnips, and (3) great power and long life. He made her a genie, like himself.

She's not under arrest -- but she's not free to go. Mulder had unrolled her from the rug and now gets three wishes.

Scully expresses some puzzlement and mild skepticism over all this.

Mulder, alone with Jenn, asks what she would wish for. She'd wish to be able to live moment to moment, watching the world go by as she drinks coffee in a coffee shop -- basically to get out of the genie business.

Perhaps unfortunately, Mulder has bigger plans. He wishes for peace on Earth. Soon he is walking through empty streets. Everyone's gone.

In an empty FBI conference room, he upbraids Jenn until she undoes his last wish. He keeps chastising her but she's gone, and Skinner and other FBI senior executives are sitting behind him.

Mulder talks to Scully, who has no memory of disappearing from the face of the Earth this morning. She suspects this is all a matter of hypnotism or the like, but notes that if Jenn really is a genie, wishing for something like world peace is not good, as it circumvents people's own lives and striving, etc.

Later, we see Jenn back with Mulder. He'd been writing out a very specific wish on his computer, but now he turns his computer off. He looks at her.

Next, Mulder is with Scully. He's rented Caddyshack. They drink beer. He tells her he didn't wish for a happier world, but she says that she's "fairly happy." What did he wish for, she asks.

We see a coffee shop. Jenn is contentedly sipping coffee, watching the world go by.
