When the icy continent splits in two, separating Manny from his family, he sets off with Sid and Diego to find a land bridge that will reunite them, but before long they run into a rowdy group of pirates.
"History’s greatest heroes return for the most outrageously funny and entertaining Ice Age adventure in two million years. When Scrat’s acorn antics cause a cataclysmic crack-up, Manny (Ray Romano), Sid (John Leguizamo) and Diego (Denis Leary) go where no herd has gone before — on a high-seas quest aboard a floating iceberg. But a menagerie of misfit pirates are determined to shiver their timbers and capsize their journey home. Join a boat-load of lovable new characters (voiced by Jennifer Lopez, Aziz Ansari and Peter Dinklage) for original songs, spectacular animation and heartwarming family fun."
