Lawn Dogs (movie, 1997)

In the affluent, gated community of Camelot Gardens, bored wives indiscriminately sleep around while their unwitting husbands try desperately to climb the social ladder. Trent, a 21-year-old outsider who mows the neighborhood lawns, quietly observes the infidelities and hypocrisies of this overly privileged society. When Devon, a 10-year-old daughter from one family, forges a friendship with Trent, things suddenly get very complicated.
