Seeing Willie and Kate reminiscing over their old stuff in the attic and show the family film footage of them attending the Woodstock festival, ALF asks Willie about the 1960s, causing Willie to ponder if he abandoned the ideals he held during those years.
The Tanner family is an average American family. One day, they discover that they have a visitor. He's small, he's furry, he's arrogant, and he's an alien from the planet Melmac. Unsure what to do, they name him ALF: Alien Life Form. Alf soon decides that as much as he misses his home planet, there's a lot to be said for Earth: the Tanners are willing to concede anything as long as he doesn't announce his presence. Oh yeah, the Tanners also have a cat, which looks rather tasty...
