One Night in... — Season 1

Three comedians. One night. No grown-ups. In this festive special, Romesh Ranganathan, Rob Beckett and Tom Allen hang out after hours and unsupervised in the famous toy shop on London's Regent Street.

The series starts inside major theme park Alton Towers where they are joined by comedian Roisin Conaty. The trio roam the Staffordshire facility's grounds and enjoy after-hours high jinks, but whether they will be brave enough to ride some of the world's most thrilling and scariest rollercoasters - such as Oblivion - remains to be seen.

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.

Comedians Desiree Burch and Guz Khan join Alex Brooker and Josh Widdicombe at the famous animal attraction. During a magical and high-spirited night, they hang out with the giraffes, feed the camels and endure the company of spiders, as they freewheel around the zoo in a golf cart and stay overnight in the zoo's lodges. As the night progresses, the friends get a glimpse into what the animals get up to after dark, and even find themselves inadvertently spying on some amorous lions, as they make the most of this once-in-a-lifetime chance to enjoy the zoo without any other members of the public present.

Alex Brooker and Josh Widdicombe are joined by husband-and-wife comedians Jon Richardson and Lucy Beaumont, as they experience the childlike joy of spending an access-all-areas night in Legoland. Alex, Josh, Jon and Lucy drink in some of the world's most impressive landmarks in Lego form, enrol in a high-octane race at the Driving School, and slip behind the doors of the Legoland staff workshop, where they have 15 minutes to build the most impressive Lego model they can.
