Manny the mammoth, Sid the loquacious sloth, and Diego the sabre-toothed tiger go on a comical quest to return a human baby back to his father, across a world on the brink of an ice age.

Manny, Sid and Diego discover that the ice age is coming to an end, and join everybody for a journey to higher ground. On the trip, they discover that Manny is not in fact the last of the woolly mammoths.

When Sid's attempt to adopt three dinosaur eggs gets him abducted by their real mother to an underground lost world, his friends attempt to rescue him.

The flightless birds and scheming green pigs take their feud to the next level.
