While in San Francisco for the promotion of her last film in October 1967, Agnès Varda, tipped by her friend Tom Luddy, gets to know a relative she had never heard of before, Jean Varda, nicknamed "Yanco". This hitherto unknown uncle lives on a boat in Sausalito, is a painter, has adopted a hippie lifestyle and loves life. The meeting is a very happy one.
Unfortunately the movie Uncle Yanco is not yet available on Disney Plus.
