A bored Isabel decides to continue hopping around people's dreams for a little excitement. Her nocturnal voyerisms reveal Liz is still fixated on Max, and Kyle thinks he will turn into an alien because Max "changed him" by saving his life. But Isabel is surprised when she is pulled into a dream she didn't choose to infiltrate: a teenage girl getting dragged, screaming, in a body bag through the woods.

Max and Isabel turn to Sheriff Valenti for help, fearing that it wasn't just a dream, but Valenti has problems of his own. An old friend from the state police is back, sniffing around about the death of Hubble, the alien hunter, and the sheriff's relationship with the Evans kids. While Kyle quizzes Tess on alien habits (and she can't resist teasing him about his fears), Isabel finally goes on a date with Grant. She falls asleep during the movie and has another "dream." Max and Isabel ask for Valenti's help once again and the sheriff sets out to find the missing girl.

When Isabel dreams it was Grant dragging the kidnapped girl through the woods Valenti goes on a manhunt to nab him. Too bad they not only got the girl's identity wrong (she shows up and wonders why they thought she was missing) but Valenti illegally searches Grant's tent and equipment. It's looking like one big hoax as the sheriff's old friend seems intent on bringing him down - the "missing" girl's family wants to sue, Grant is suing and a judge threatens to throw Valenti in jail.

Isabel has another dream and this time, she knows where the girl is being hidden. Max, Isabel and Sheriff Valenti head out to the woods and quickly discover her buried, her head covered in glass with an air tube attached to feed her oxygen. As they are digging her out the kidnapper is waiting. He shoots but Max throws up a shield to block the bullets as Valenti and Isabel free the girl.

Later, after Valenti's repeated warnings about Sorenson, FBI Agent Duff links Sorenson to all the items found at Laurie's kidnapping scene, by comparing his whereabouts to items that were listed as stolen.

Liz theorizes that the blue crystalline rock is some sort of parasite. She enlists Isable's help to find out about Frazier Woods from Sorenson.

Michael and Maria take Laurie to the Tucson estate of her grandpa. Her aunt and uncle are shocked at the resemblance of Michael to their father, thinking he may be an illegitimate son. They remind Laurie that her grandpa died seven years earlier. While Laurie is secluded upstairs, Uncle DuPree pays off Michael with $50,000 so he doesn't claim inheritance, and throws Michael and Maria out.

Liz, Max and Isabel deduce that alien parasites are living in the water in Frazier Woods, near their original crash site.

Brody, embodying the otherworldly ally "Lorek," comes to the Crashdown to tell Liz, Isabel, Tess and Max the alien crystals infect certain humans with a chromosomal flaw. The queen parasite of the Ghandarium colony is the only one that can infect. Once infected, the parasite spreads like the plague, killing all humans in contact with the first one infected.

Meanwhile, back in Tucson, Michael and Maria are staking out the DuPree estate. They get back into the house, and Laurie tells them her aunt and uncle need her "to be crazy." After being thrown off the premises again, Michael and Maria search public recrods, finding out that the DuPree estate was left in Laurie's name by her Grandfather. Maria confronts Laurie's aunt about ownership of the estate. Laurie tells Michael about her grandfather, taking him downstairs into the estate's bomb shelter to see her grandfather's possessions. Her grandfather was "taken" by aliens. Laurie explains her recessive genetic chromosomal defect, a trait that she shares with her grandfather.

The gang back in Roswell start digging in Frazier Woods. Kyle and Alex find the Ghandarium parasite colony. As they descend into the hole, the opening closes up with crystals, trapping them below. Isabel, Max and Tess are powerless to break through the crystals. To aid in freeing Kyle and Alex, Isabel volunteers to go to the UFO Center to retrieve Brody's tools. While trapped, Kyle and Alex discover the crystals can't live without oxygen.

Grant Sorenson overcomes Isabel at the UFO Center, kidnapping her. As they drive in his truck, he asks for Isabel's help. She realizes he is being controlled. as he tells her they are going to Tucson, but he doesn't know why. Isabel knows then that Grant is infected by the queen of the Ghandarium colony, Grant says he is supposed to kill Isabel, but can't, and leaves her on the side of the road.

Back at the DuPree mansion, Michael finds the maid strangled. He sends Maria and Laurie to the safety of the underground bomb shelter. As Michael searches the house, he is shot by Grant. Just then Sheriff Valenti and FBI Agent Duff arrive. Grant has found the girls in the bomb shelter, and holds a gun to Laurie's head. Sheriff Valenti talks him out of the gun. He points the gun at the sheriff, and FBI Agent Duff shoots Grant. As he lies dying, alien crystals explode from Grant's chest, and the queen alien of the colony propels out from inside him. As all run outside the door, Michael uses his powers to pull all the oxygen from the bomb shelter. The queen alien goes into a frenzy and dies.

Back in Roswell, the crystals in the ground begin to melt, dying. Kyle and Alex free themselves, commenting they have "saved the world."

Back in the bomb shelter, Isabel returns to sit with Grant's body.

Sheriff Valenti and FBI Agent Duff talk about the incident that "never happened."

All is resolved as Michael and Maria get a lawyer to help Laurie regain her estate from her aunt and uncle.

At the casino, while Kyle is winning, Alex loses $3000 in one hand of blackjack. Michael heats up the craps table. Liz and Tess can't even get into the casino, 'cause security suspects their IDs to be fakes.

Turns out Michael was cheating at craps, using his powers. Although Max warns him of the suspicious pit boss, Michael will not avoid confrontation. Both Michael and Max end up in jail, calling Maria to bail them out. While in jail, Michael and Max argue about leadership, responsibility, and mostly their friendship. When they return to the suite, Max decides to leave, to go back to Roswell. He says good-bye to Liz at the video arcade. On his way out, he sees a bride and groom in a cab, and is flashed a vision of Liz with him as the happy bride and he the groom.

Just as she starts complaining about him, Michael, who has been the usual bad boyfriend, ignoring Maria most of the time, surprises her with an introduction from the ballroom stage to sing for the nightclub crowd. As Maria fulfills her on-stage singing fantasy, Kyle and Tess dance, Isabel and Alex dance, and Max returns and he and Liz dance. Max tells Liz of his "married" vision.

When they return to their suite, Sheriff Valenti is waiting. He found out they were all missing, and was worried. They all get a stern lecture and are told to go back to Roswell, ending the fun.

Max and Michael make amends, as they spend the last of the $50,000 DuPree money on coffee. Max tells him he feels responsible for the four and shares, "Without you, I'd be lost, Michael." Michael replies "Whoever sent us down here was smart...because they sent us together. As long as we stick together, we're going to make it."
