Mr. Sandman: ALF (TV Episode)

Plot

ALF and Willie (Max Wright) come into possession of a treasure map, left to Willie by his great-great-grandfather. In a twinkling, the duo has packed their mining equipment and are off to Death Valley. Before long, however, the heat and the desolation begins to wear Willie down--and the effect on ALF brings a whole new meaning to the words "alien environment". ~ Hal Erickson, Rovi
