It seems every alien race has a hidden agenda anymore, and the 20th "Enterprise" episode will feature what could be quite possibly the 20th hidden agenda.

According to a spoiler report from TrekToday, "Oasis" will be airing during May sweeps just before the first season finale of the popular Star Trek show, and will reportedly feature guest appearances by "Hollywood Squares" host Tom Bergeron as well as Rene Auberjonois, best known to genre fans as Constable Odo in "Star Trek: Deep Space Nine."

Bergeron's character, D'Marr, will be featured in the opening of the episode sharing dinner with Capt. Archer (Scott Bakula), Sub-Cmdr. T'Pol (Jolene Blalock) and Cmdr. Trip Tucker (Conner Trinneer). D'Marr is trading silk and spices, but the crew is more interested in duratanium to patch fractures in the Enterprise's hull. D'Marr informs them that there is a ship that crashed in a nearby star system that has plenty of the material they need, but warned that she ship is "haunted."

When the away team arrives, they find no life signs, but a breathable atmosphere on the ship. The team splits into two to explore the trip, but then everyone starts seeing strange things.

At one point, Tucker notices a small hatch blow away, which reveals an oasis with trees, water and food, but it is completely deserted. While Tucker explores, however, she finds a woman through the foliage. When he and T'Pol chase after her, they suddenly are surrounded by an alien group known as the Kantare. They apparently have been stranded on the planet for three years, and created the oasis to shield themselves from alien attacks and provide the necessary tools they needed to survive.

Tucker apparently becomes involved with the woman he first saw, Liana, which draws a little bit of jealousy from T'Pol. When they return to the Enterprise, Archer tell Tucker that an analysis of the hull plating of the ship has revealed it's been there for a bit more than three years ... it's really been there for 22. He also tells Trip that there's an escape pod in orbit, which they are bringing into the ship.

Meantime on the planet, T'Pol makes a discovery about the Kantare that they didn't want to let out, and she is captured.

The episode was written by executive story editor Stephen Beck based on a story by Brannon Braga, Rick Berman and himself. This will be the second script for Beck following "Cold Front." "Oasis" is being directed by Jim Charleston, best known for his work on "The District."

Please note that none of the above has been confirmed by Paramount Television, and should be treated as any other rumor would.
