Several boys aged seven to fourteen, have formed their own secret support group as a result of parental neglect and abuse. The group is however more keen on revenge against the adults on their island. They break into houses and steal items, not for money, more for the thrill. They vandalize homes and torment the occupants. One man decides to seize the opportunity to do away with his wife and blame it on the intruders.

The Pickles family welcome a new arrival, Dil, whose constant crying and need for attention quickly exhaust the other toddlers. Seeking to return the "broken" baby to the hospital, the gang embarks on a journey in a Reptar Wagon that inadvertently veers off course, leaving them stranded in a vast, dangerous forest. While facing off against escaped circus monkeys and a predatory wolf, Tommy must overcome his own resentment to protect his brother and make it back home.
