YouTubers Matt and Rebecca return to their channel after completing a 48-hour challenge. They find a puzzle box left by the "Game Master" in their backyard, which they had discovered before even knowing the Game Master's identity. As they try to open the box, they notice strange occurrences outside, including a tent and a red truck, and a worker reveals that the Game Master sent them to pour concrete to prevent the Quadrant from digging in their backyard.
After opening the puzzle box, they find a SanDisk flash drive with a message from the Game Master. The message warns of a threat to YouTube called the Red Hood, who has created a mind-controlling substance called the Red Mixture. The Game Master provides coordinates to remix the Red Mixture and save RZ Twin, who has been affected by it. Matt and Rebecca also learn that the Red Hood has taken over the Fun Box, a location they had previously visited.
The Game Master sends them a message with a 15-minute time period to take over the security system, and they must navigate the Fun Box to find the ingredients to remix the Red Mixture. With only one minute to get to the door, they rush to enter the Fun Box and begin their mission to stop the Red Hood. The video ends with a cliffhanger, as Matt and Rebecca hide from the Red Hood and prepare to find the ingredients.
