The animals are trying to avoid the ice age by migrating south. Sid, a clumsy sloth left behind by his family, is attacked by two Brontops whom he angered. Sid is soon saved by Manfred ("Manny"), an agitated mammoth who fights them off. Not wanting to be alone and unprotected, Sid follows Manny.
Meanwhile, Soto, the leader of a Smilodon pride wants revenge on a group of humans by eating the chief's son, Roshan, alive. There is an attack on the human camp, causing Roshan's mother to be separated from the rest when she falls over a waterfall. Soto's lieutenant, Diego, is sent to find and bring the baby back. Sid and Manny spot Roshan and his mother near the lake, having survived her trip over the waterfall.
The mother only has enough strength to trust her baby to Manny before she disappears.
