During a summer vacation at his aunt’s house, Johnny is made responsible for taking care of his older cousin Remember, who has autism. Remember is a gawky awkward kid with some pretty strange habits, like repeating back almost everything Johnny says and spending hours glued to the weather channel. Johnny’s premonitions of disaster appear at first to come to fruition, but when the two boys save a bully from drowning, salvage the pizzeria guy’s romance, and share girl troubles, Johnny ends up having the summer of his life.
