Plot summary

With Scrat marooned in deep space, triggering an endless string of cosmic events, the mismatched band of prehistoric friends--Manny, the woolly mammoth; his mate, Ellie; Diego, the sabre-toothed tiger, and Sid, the well-meaning sloth--get ready for Peaches' engagement. Now, after the events of Ice Age: Continental Drift (2012), only a cataclysmic incident of epic proportions could stop the wedding. However, fate has other plans for them: Manny's secret wish is about to come true. Before long, strange shooting stars reach the Earth's atmosphere. These unprecedented phenomena threaten to wipe out all life forms unless a trusted companion from the past lends a hand with his specialised scientific expertise. This time, things are getting hairy.
