One Night In... | Preview (Channel 4)
In this comedy access series, Alex Brooker and Josh Widdicombe spend the night in some of the UK's most exciting attractions.
In each episode, Alex and Josh are joined by comedian friends as they are locked in overnight, free to make mischief and have the run of the place, with no grown-ups to hamper their fun.
This time, Alex, Josh and comedian Roisin Conaty are let loose inside the UK's largest theme park, Alton Towers. Alex, Josh and Roisin roam the theme park's grounds and enjoy after-hours high jinks, but are they brave enough to ride some of the world's most thrilling and scariest roller coasters, including Oblivion?
The next episode will be available on All 4 straight after the transmission of Episode 1.
