It's 1975 and Alex Mitchell has just sat down to watch his favourite comedy show when the unbelievable happens. After a particularly hilarious skit, Alex starts to laugh uncontrollably, so much so that he ends up having a heart attack, dropping dead there and then. Brace yourself for The UnBelievable with Dan Aykroyd. Each hour-long episode opens up a cabinet of curiosities to reveal the strangest true stories in human history. Watch as these tantalising tales come to life through dynamic recreation, compelling graphics and arresting archival. From Boston's Great Molasses Flood to a man who survived being struck by lightning seven times, these seemingly-fictitious stories all actually happened. It's a bizarro barrage of people, places and events that proves just how weird our world can be.
