Enterprise encounters a large, otherworldly vessel unlike any the crew has seen before. They try to make contact with it, but to no avail. Suddenly, a large portal opens and the ship "swallows" Enterprise, rendering its weapons and engines useless. Luckily, life support is still operational. Archer, Trip and Reed take a shuttlepod into the cavernous ship for further exploration. Although there doesn't seem to be any immediate threat to Enterprise, Trip is suddenly attacked by a colorful wisp of smoke that seems to invade his body for a few seconds before releasing him. Back in Sickbay, Trip insists that he's fine. He explains that during his brief encounter with the alien wisp, he had an out-of-body experience and believed he was in Florida and visiting an old girlfriend.
