Elvis and his band members go into a hall of mirrors at a carnival. Colonel Tom Parker follows him inside and when Elvis gets confused by all the reflections, Parker says Elvis is lost but he can help him find his way, meaning he can help him deal with all of the fortune and fame he's going to experience. Parker then opens a door and they walk outside where Parker asks Elvis to let him represent him exclusively.
