A tyrannical school principal terrorizes his fragile wife with heart disease and his cynical mistress as well (both are teachers in the couple's private school). The two women plot to kill him, but after the murder their plan starts to fall through. The body disappears, then more and more signs become apparent to prove: he is alive.
The real mystery is why anyone had to remake a classic French thriller that was imitated so many times before, why it had to be done so terribly, cast so wrongly and acted in such unsubtle way - and why anyone on earth should care the whole stuff.
