The Bears spend a day hanging out with Chloe inside their cave, when the news comes on the TV and forecasts a heavy thunderstorm incoming. As the weather gets worse and worse, Chloe video chats with her parents and asks them if she can spend the night with the Bears. Despite her father being reluctant about the idea, they approve under the condition that the Bears protect Chloe at all costs. They then call it an official slumber party.
After a little fun, the group sets up a blanket fort. Inside, Chloe decides to tell the Bears a scary story about a Slug-Man that freaks them out. They become paranoid about having a break-in when they hear noises in the kitchen. Out of fear, they urge Chloe into Panda's room and tell her to stay. Grizzly decides to update her parents on the situation, only to find there's no signal. Panda tries to use his phone, soon realizing he had left it in the fort.
They decide to go out and grab the phone together. They manage to retrieve it, but are scared back into the room by another noise. When they arrive back inside, they find Chloe missing. She had slipped out of their supervision to the source of the noise. She finds it was only a confused raccoon scavenging their kitchen for food. After setting it free, the power goes out. Then, the Bears and Chloe start hearing strange noises coming from outside. To try to prove there's nothing there, Chloe opens the curtains, and a lightning strike reveals the silhouette of a tall, dark figure. Believing it to be Slug-Man, Chloe screams, and Ice Bear picks her up and takes her to Panda's room. While they are panicking, the figure goes to the window and knocks on it.
They run to the living room and hide under the blanket. Convinced it's the Slug-Man, the Bears and Chloe panic even more. The figure moves to the door, and tries to open it. Chloe, terrified, hugs Grizzly and the Bears remember they promised to protect her. Running out from the blanket, the Bears push against the door, before realizing it opens outwards. The fall onto the ground where the figure is towering above them. Grizzly yells at Chloe to save herself, but instead she grabs a book, climbs up the door and hits the intruder on the head, rendering him unconscious.
The power turns back on, and Chloe realizes that it's not the Slug-Man, but rather a human. The man turns around, and reveals to be Chloe's father. Shocked, Chloe apologizes for attacking him, and asks what he's doing there. Her Dad tells her he got worried about her, so he went to pick her up. He then admits to being too worried. Chloe then tells him she was scared, and was happy he came. The Bears apologize for screaming and running away.
After another lighting bolt strikes, Grizzly suggests they stay until the storm stops. The episode ends with them all having a pillow fight.
