A young photographer has fallen in love with his girlfriend's sister, throwing the trio into chaos.

In May 1968, no one passes him by: day and night, Peter Ernst Eiffe, who grew up in a Hanseatic family, is on the road in Hamburg with the felt-tip pen and covers toilets, traffic signs, mailboxes with his sayings. Presumably he is the first graffiti tagger in Germany. Highlight of his career: He drives a Fiat Topolino into the Wandelhalle of the main station and proclaims the "Free Republic of Eiffe". Forcibly admitted to psychiatry, he founded the party »Eiffe Brothers«. Christmas 1983 he escapes from the institution and is found frozen months later. In the 1990s, the filmmaker Christian Bau and Artur Dieckhoff began to deal with Eiffe.
