Permanent Vacation (2007)

A camping trip results in some twisted family memories in this off-the-wall black comedy. Hoping for one last family vacation before his children leave the nest, laid-back dad Eric Bury (Frank Harper) takes his brood to a trailer park teeming with oddballs. The clan's plans for a relaxing holiday go down the drain as they encounter sex addicts, a sadistic cop (Michael Bowen), decapitated corpses, bloodthirsty fish and a sage (David Carradine).
