The movie begins with typical tensions, resentments, and competitions between two brothers, age 6 and 10. Their father is divorced, and their teenaged sister is distracted by her interest in boys and parties.

The movie does attempt to address sibling rivalries, the self-esteem issues that can develop, and the importance of two brothers learning to look out for each other.
