The life of several people whose lives revolves around a typical Montreal Guest House at the "Plateau-Mont-Royal" district. The main caracter, Symphorien, is a naive but sympathetic fellow, who is the janitor for this guest house run by Mrs. Sylvain, a single yet bumbling lady who runs the house in a strict, efficient way. However, she has sometimes some conflicts with one of the boarders, Ms L'Esperance, whose man-hunting tactics does not make unanimity all the time. And also endures a wacky undertaker, Oscar Bellemare, who woos Ms L'Esperance despite the warnings from his mother, an extreme conservative lady, who will marry a "snob from the West" later.
