King of California

After spending several years in a mental institute Charlie (Michael Douglas) is sent home, reuniting with his teenage daughter Miranda (Evan Rachel Wood). Charlie becomes obsessed with the notion that a long-lost Spanish treasure is buried underneath their local suburban California Costco. Disconnected from reality and his daughter's life, Charlie's erratic behavior further strains their relationship and completely disrupts her peaceful existence. Initially skeptical, Miranda soon finds herself joining in Charlie's questionable antics in an effort to believe in her father and give him one last shot at accomplishing his dreams.
