An episodic film, telling four erotic tales: Angela isn't sexually satisfied by her husband, so she simulates sleep-walking to visit her neighbor across the street every night; when his bathtub runs over, shy Peter gets to meet his sensuous neighbor Lolita; at a high-school reunion his former students pull a prank on Prof. Hellberg and make him believe he cheated on his wife while being drunk; Sybill has a good time during a break at the opera with the famous conductor Cramer.

A man starts playing a piano. Neighbours who hear the music are drawn to it and begin dancing, dropping what they are doing to join the impromptu dance party.
