PREMISE: Darren Barrenman is a hapless dreamer and would-be philosopher who spends his days looking after the pool of the Tahitian Tiki apartment block in sunny Los Angeles and crashing city council meetings with his neighbors Jack and Diane. When Barrenman uncovers the greatest water heist in LA history since Chinatown he makes uneasy alliances with a beautiful and connected femme fatale while following every lead he can with corrupt city officials, burned out Hollywood types, and mysterious benefactors - all in the name of protecting his precious Los Angeles.
The description makes me think of The Great Lebowski.
The Dude + Chinatown
