Six years ago, the lovable intergalactic fugitive Gordon Shumway, best known as ALF, was on his way back to his new home when the Alien Task Force finally caught up with him. Now, he is being studied at a top-secret military base where he finds allies who feel that ALF's existence should be announced to the world to ensure his safety... especially when they learn that the abrasive Colonel Milfoil wants ALF, and all Alien Life-Forms, destroyed.
