Twenty-three-year-old Louise, a counselor at Camp Emerson, awakens early to discover that Barbara Van Laar, one of her campers, is missing. She thinks through the previous night. A dance was held, and Louise counted all the campers as they returned to the cabin at the end of the night.
Now, Louise wakes her counselor-in-training, Annabel, who is hung over and vomits into a potato chip bag. Louise realizes that Annabel snuck out the night before, just like she did. She gathers an empty beer bottle and a marijuana butt, tossing them in the potato chip bag. Then, she reenters the main part of the cabin and pretends to discover for the first time that Barbara is missing.
