This is a highly amusing and effective infidelity comedy, where A cheats on B with C whereas B cheats A with D who then cheats on E with B. It may sound very schematic but it is not the slightest. It is actually surprisingly recognizable. The wives believe that their husbands are jogging and playing dart, which obviously they are not. But even if the cheating husbands are somehow self-inflicted, the women are still left with their own share of the enjoyments.
