The UnBelievable with Dan Aykroyd explores some of the strangest people, places, objects and events in human history. The series reveals stories that are as surprising as they are true. From Boston’s Great Molasses Flood of 1919, when 2.3 million gallons of syrup devastated a neighbourhood, to the notorious tonsil guillotine, an 1800s medical instrument designed for self administered tonsillectomies, and Franklin D. Roosevelt’s Second World War plan to use bats to bomb Japan, the series uncovers history’s most bizarre moments.
