Paul Carlson is an anthropologist/geologist uncovering some Native American pottery in New Mexico. He's joined by his former professor/friend Johnny Longbow and two of his graduate students. There's also Kathy Nolan, a local reporter, who is immediately smitten with Paul. On the television we see newscasts about an asteroid striking the moon and that there will be a big meteor shower in a few days. When Paul and Kathy are out in the hills, on a date, they witness this light show-and he's grazed by one of the meteoroids, which begins to transform him into a reptilian monster that kills humans. He first kills a drunk man having a fight with his wife, then rips apart some campers from limb to limb. When he changes back to a human he doesn't remember what he's done.
The authorities, however, begin to think that a monster is killing people, as there are huge footprints and claw marks about the murder scene. In the end, they have to try to destroy Paul and the only way to do it is with an arrowhead fashioned out of the same type of moon rock that created him. So his best friend, Johnny Longbow, has to fire the fatal shot, in which there are a lot of video effects from the land of cheap effects.
TRACK OF THE MOON BEAST is an interesting movie, surprisingly violent, but the monster itself is a lackluster man in a suit (which looks like Don Dohler's NIGHTBEAST) and the acting is incredibly wooden.
