List of episodes

Incorporeal beings attempt to take over the Earth starship Enterprise. At the start of the episode Enterprise is taken inside an enormous alien spacecraft of unknown origin, and the aliens take over various crewmember's bodies.[2]

Later in the episode the crew takes shelter in the catwalk, which has enhanced shielding.


While at warp speed, a huge alien vessel overtakes and swallows Enterprise, disabling the ship's engines and weapons. When the scanners register neither the alien ship nor its numerous energy-wisp-like incorporeal beings, Captain Archer takes Lieutenant Reed and Commander Tucker on an away mission to the interior. While there, Tucker is visibly "entered" by one of the beings before being returned to his normal state. Doctor Phlox's examination reveals no lingering effects.

Later, Tucker is possessed again, and is soon located in the mess hall enjoying the simple pleasures of food. When asked, the alien possessing Tucker says that they are explorers who merely want to experience the tangible nature of the corporeal state they long evolved from. In exchange, the crew would be permitted to have out of body experiences by "crossing" in to the incorporeal realm. Archer, doubtful of the aliens' intentions, demands the release of his ship, and the return of Tucker's consciousness, both of which quickly happen. Enterprise is now freed, but the engines are not operational. While making repairs, the crew starts displaying signs of possession one-by-one. Similar events occur throughout the ship, including the takeover of Reed, Ensign Sato, and 22 others.

Ensign Mayweather, pursued by one of the aliens, finds sanctuary in the nacelle catwalk area, so Archer orders the uninfected crew there. Sub-Commander T'Pol then proposes a plan to use her more disciplined mind to try to uncover the beings' intentions. Archer is opposed, but assents given that there is no alternative. T'Pol is soon overcome and discovers that the aliens plan to co-opt the 82 crew-member's bodies to save themselves from their failing ship. Archer, T'Pol and Phlox then hatch a plan to forcibly expel the beings by asphyxiating the infected crew. Though he has some trouble with an infected Tucker, Phlox is able to reach the atmospheric controls and floods the ship with carbon dioxide, and the aliens are forced to return to their ship. When the alien ship attempts to pursue Enterprise, Archer destroys it with two torpedoes.


Rick Berman described the episode as a "heavy science fiction episode that I'm very pleased with. That's the one with our 'wisps' that will remind people of the [alien clouds] from The Original Series."[3]

The episode was filmed over seven days. Existing standing sets were used, including the Bridge, Ready Room, Mess Hall, Engineering, Corridors, and The Catwalk sets were also reused. A part of the alien vessel was constructed and extended using greenscreen and computer-generated imagery in post production.[1]


The Crossing was first broadcast April 2, 2003 on UPN. It had an average of 3.9 million viewers.[4]

Television Without Pity gave the episode a grade C.[5][6][7]

This episode was nominated for an Emmy Award for Outstanding Special Visual Effects for a Series.[8][9]
