A documentary on Heinz Hermann Polzer, better known under his pseudonym Drs. P. Polzer was a Swiss singer-songwriter, poet, and prose writer in the Dutch language. His oeuvre consists mainly of macabre novelty songs, with dry humour, surprising twists and an exceptionally inventive and virtuoso use of the Dutch language. Polzer sang his lyrics with a distinctive shaky voice, while accompanying himself on the piano.

Songwriter and entertainer Drs. P. often let his public roll over the floor with laughter with his absurd songs, but his personal life also knew a dark side. The documentary 'De Terugkeer van Drs. P.' (The Return of Drs. P.) doesn't simply show a hilarious but also a painful image of the virtuoso who rarely showed anything of his personal life.
