"Back in the 1950s, Swedish-American singer William Clauson had a worldwide hit with 'La Bamba.' Now he lives in a ramshackle garage in Tijuana, Mexico. In William, the New Judo Master, directors Ricardo Silva and Omar Guzmán show how a Mexican nurse washes his naked old body. 'How did we get here?' a voiceover muses. 'What road led us here? When did we take it?' This fascinating film essay is about the struggle against time, old age, and transitoriness.
