Manny, Sid and Diego are back for a fourth adventure after their continent is set adrift. The group set a course for home using an iceberg as a sea vessel, however a band of pirates look to halt their expedition… Scrat's nutty pursuit of the cursed acorn, which he’s been after since the dawn of time, has world-changing consequences – a continental cataclysm that triggers the gang's greatest adventure. In the wake of these upheavals, Sid reunites with his cantankerous Granny, and the herd encounters a ragtag gang of seafaring pirates determined to stop them from returning home.
