Great news - Kevin McCallister (Macaulay Culkin) is spending the holidays in New York City! Bad news - his parents are spending them in Florida! Separated once again from his family, Kevin manages to find food, lodging and fun using his dad's credit card. But his big-spending solo act takes a dangerous turn when the Wet Bandits, Harry and Marv (Joe Pesci and Daniel Stern), escape prison and also land in the Big Apple. Now, Kevin must outrun and out-prank them again in this high-flying adventure with twice the ingenuity, twice the kid power and twice the laughs as the original!

In the winter of 1982, a twelve-man research team at a remote Antarctic research station discovers an alien buried in the snow for over 100,000 years. Soon unfrozen, the form-changing alien wreaks havoc, creates terror and begins killing the researchers one by one.
