While on a grand world tour, The Muppets find themselves wrapped into an European jewel-heist caper headed by a Kermit the Frog look-alike and his dastardly sidekick.
Kermit and his friends go to New York to get their musical on Broadway only to find it's a more difficult task than they anticipated.
The Muppet characters tell their version of the classic tale of an old and bitter miser's redemption on Christmas Eve.
Gonzo is contacted by his alien family through his breakfast cereal. But when the men in black kidnap him, it's up to Kermit and the gang to rescue Gonzo and help him reunite with his long-lost family.
