Lucie the Quebecker and Nicole the Frenchwoman with the "funny accent" are both twenty-six, single and share their Montreal apartment as they share their joys and sorrows. The first works in radio, the second in an airline company, and both have a married lover who, every Friday evening, rushes off to a home that has been forsaken for a while, saying: "Bye, see you Monday"...
