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 Charlies questionable antics in an effort to believe in her father and give him one last shot at accomplishing his dreams in this darkly funny, exciting and surprisingly hopeful take on the modern family and the American dream.
Charlie's convinced a buried Spanish treasure lies beneath the local Costco (one of many companies given costar billing; others include McDonald's, Petco, Target, and Chuck E. Cheese). The plot follows Charlie's single-minded, impossible-dream journey, while the world-weary Miranda is resigned to following ("Time to get on that old bipolar pony and ride," she mutters). But along the way, dad and daughter find true ways to reconnect, and therein lies the true majesty of King of California --A.T. Hurley
