The trailer shows a blizzard, while Scrat tries to get through it, when he notices his acorn. After several struggles to get to it, he is frozen when the blizzard stops. He manages to pop open his eyes, and leans toward the acorn handle. He successfully pulls it out, after an explosion. Feeling around with his foot, he finds out that he has made a hole in the ice, and begins to fall. After hitting a few trees, he slides down to the tip of a scaly back and tail, losing the acorn. He slides down to the tip of the tail as it rises, to come face to face with a Tyrannosaurus rex. The end of the trailer shows the Tyrannosaurus rex roaring at Scrat and cuts to the inside of the Tyrannosaurus's mouth, where Scrat is seen, his eyes twitching.
