The Ricardos and Mertzes finally head for Europe on the U.S.S. Constitution. Everything looks normal as they board the ship and hear the announcements and fog horns - giving warning that the ship will leave soon. Lucy has to say one more goodbye to Little Ricky with his grandmother. She gets tangled up and the ship starts to move. Ricky tries to help to no avail.
After a series of gaffs, Lucy take a helicopter to land on the deck of the Constitution. More funny interplay with the Pilot and the landing is near. More fun ensues, until Lucy is safe on deck with Ricky. Lucy is the star of this show and jumps right in. One of the best episodes!
