Soon, a particularly rare butterfly catches her eye and she wanders into the woods in hot pursuit until it suddenly disappears. When Kelly turns back, she realizes she is completely turned around with no idea how to get back to her friends. Armed with only a mason jar, a butterfly net, and a small lunch, Kelly is forced to contend with the wilderness and many of the dangers therein.
