The strange mask that gave Jim Carrey remarkable powers in the 1994 hit The Mask makes a mess of a seemingly ordinary family in this special effects-laden comic fantasy. Tim Avery (Jamie Kennedy) is a cartoonist living quietly in suburbia with his wife Tonya (Traylor Howard), their baby son Alvey (Ryan Falconer), and dog Otis; however, their lives are turned upside down when Otis discovers a strange green mask which channels the spirit of Loki (Alan Cumming), the Norse god of mischief. Both Otis and Alvey get their hands (or paws) on the mask, and soon both are shape shifting and making all manner of trouble while having a great time doing it. Unfortunately, this isn't the end of Tim and Tonya's troubles -- it seems the supreme Norse god Odin (Bob Hoskins) has given Loki the assignment of recovering the mask, and Loki will do whatever he must to get the mask back from Alvey and Otis.
