A film featuring the veteran soul music artists and music of Stax Records. It tells the story of soul, a musical genre that was to have a major influence on other styles of music for decades. Ten legends of soul talk about the beginnings and still show at their concerts today that, despite their advanced age, they have lost none of the energy and joie de vivre that defines this music.

Bandleader Kay Kyser takes his troupe of nutty musicians, goofball comics and pretty girl singers on a tour around the world to entertain the troops during World War II.
