Big Jim seems to have turned over a new leaf, convinced that the dome saved his life. They have an immediate problem when Rebecca determines that the influx of butterflies has led to a massive increase in the caterpillar population with half of their local crops now infested. Rebecca wants to burn half of the crop to save the rest but Big Jim decides that with the infestation the dome is testing him. He has another plan. At the high school, Junior finds Angie's bloodied corpse. They also find a woman's bloody shoe print. Junior thinks his father is responsible but Joe saw him asleep at home. Sam reveals to Julia that his late sister was Big Jim's wife. He also shows her the sketch she made that appears to be the girl Julia rescued from the lake.
