Beet (2003)

A family is on summer vacation. Their adolescent son is a mixture of bored and horny. A yellow jacket wasp joins them in their car and then at their vacation campsite. A sultry young woman is doing laundry outdoors just as a brief, torrential downpour occurs and the wasp allows her to reveal, much to the young man's delight, her special knowledge of how to deal with insect bites.
