Leon, an 'unemployed idiot', lives in a building whose inhabitants are trying to clear up a murder that has taken place. Part of their plan involves persuading Sylvie, a striptease artist, to become Leon's girlfriend, since he is their chief suspect. Sylvie wants a career as an actress in return for her undercover work. As the plot unfolds, we learn that she is the one who really committed the murder. She and Leon flee to Australia, a place he has always dreamed of, where they raise their daughter. Time becomes distorted in the final act as Leon is thrown into utter confusion.

The different 'neighbour' characters and situations reveal a wealth of absurd, ludicrous scenes from everyday life, familiar to all. This little community fills the spectrum of roles found in any community: the crowd of 'average people', two roles that represent conscience and common sense - a judge and a director - and two outrageous, fringe characters: Leon and Sylvie. The absurdity of the situations and abrupt changes of dialogue offer a reflection and caricature of our daily lives, eliciting 'laughter of relief'. The realistic and surrealistic are woven together gracefully. The course of events 'between neighbours' remains unpredictable, while the final (dreamlike) twist takes the main character, Leon, to Australia, the land of his dreams. At this point, we are no longer in the realms of the familiar, and follow the 'neighbouring' path laid out by the author, leaving us to imagine a thousand possible endings to the play.
