Comedian Aisling Bea joins Alex Brooker and Josh Widdicombe inside one of London's most epic and iconic buildings - the Natural History Museum. The trio are awestruck by the splendour of the building as they scoot through its epic corridors, enjoy a game of hide-and-seek, muck about in the lavish exhibitions and raid the gift shop. While exploring the facility's off-limits areas, they stumble across the strange and spectacular basement Tank Room, housing the gruesome-looking collection of `wet specimens" - a multitude of species preserved in jars of alcohol. This somewhat gothic, creepy experience only increases the trio's giddy delirium.
