The Greenes take a detour, courtesy of Dinah's navigation, and wind up in Roswell, New Mexico, at the A-Lee-Inn Cafe, a hangout for UFO-seekers, where they encounter eccentric people who gather every year for an alien-sighting event. Meanwhile, Russell learns the secret of an astronaut's disappearance.
