the film: ICE AGE

The film begins with Sid, a clumsy ground sloth left behind by his family, is attacked by two Brontops whom he angered. Sid is soon saved by 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 the mother to be separated from the rest. Soto's lieutenant, Diego, is sent to find and bring the baby back. Sid and Manny spot Nadia near the lake having survived her trip over the waterfall. She has only enough strength to trust her baby to Manny before she disappears. After much persuasion by the sloth, they decide to return Roshan but when they get to the human camp, the humans are gone. They meet up with Diego, who convinces the pair to let him help by tracking the humans. The four travel on, with Diego secretly leading them to an ambush. Soon they reach a cave where Sid and Diego learn about Manny's past and his previous interactions with the humans, where his wife and son were killed, leaving Manny a cynical loner.
At the end of the film, Diego, Manny and Sid battle Soto's pack and a short fight ensues. Diego fights against Soto, and Soto knocks Diego out. As Soto closes in for the kill on Manny, Diego leaps and stops Soto, who wounds Diego in the process. Manny, in vengeance, knocks Soto into a wall of rocks, where sharp icicles fall on Soto, killing him. Manny and Sid manage to return the baby to his tribe before but Diego return with the group and they return the baby with her father.
