Tartuffe

Tartuffe, a pious fraud, is lodging with Orgon and his family, ingratiating himself to such a degree that they are initially blind to his true designs, which include marrying Orgon's daughter whilst seducing his wife. When the family realise what Tartuffe is up to, they set about exposing his despicable plan. However, Orgon won't be so easily persuaded, and names Tartuffe as his sole heir. When Orgon finally discovers the truth about Tartuffe, it comes too late.
