Plot synopsis: Netflix has confirmed a new comedy series featuring an "all-star line-up" of comics and celebrities. Hot or Cold will be led by Taskmaster and Last One Laughing stars Bob Mortimer and Richard Ayoade, which takes place in a "mysterious institution". However, there is a twist in that "challenges that appear to make no sense", with the pair's only guide being the room they're in, which will light up red when they're getting warmer and blue as they get colder.
