In the seemingly quiet town of Bere Knighton there is never a dull moment for Dr Richard Forth. Not only does he have a hectic work schedule and an awkward friendship with his ex-girlfriend, but his wife, Barbara, is constantly ill and nobody knows what is wrong with her. When Eric Dawson, a stranger, claims to have known Richard's second fiancee - a woman Richard claims does not exist - Barbara's health worsens and she isn't the only one. With bad luck spreading almost as quickly as bad news, it seems somebody is out to kill Barbara, and anyone else who gets in their way.
