A group of friends, including YouTubers Team 48 and others, participate in a horror-themed challenge where they have to survive for 30 minutes in a house while being chased by a person dressed as Pennywise, also known as "IT." The twist is that IT is blindfolded and has to rely on sound to catch the participants. As the game progresses, the participants start to get caught one by one, and the remaining ones have to work together to survive until the end of the 30 minutes.
