Essentially a comedy of embarrassment and errors, The Worst Week of My Life began with the seven days leading up to the marriage of businessman Howard Steel and his fiance, the daughter of a high-court judge, Dick. Humiliating situations ensue: Cassie, a work colleague who Howard had a drunken one-night stand with two years earlier, sets out to snare him and becomes obsessive; Howard accidentally kills his in-laws' dog, puts Mel's granny in hospital and loses the wedding ring (a family heirloom). At the end of the first series, Howard and Mel were wed, despite the many mishaps that had befallen the well-meaning but accident-prone groom.
