Orphaned, Marguerite was taken in by her guardian, Sir Evérard, in the Malbackt estate in Scotland. The luxury of the residence, isolated in a wild nature, did not succeed in dispelling the intense uneasiness that seized the young Frenchwoman upon her arrival.

Marguerite has no sympathy for Sir Evérard, a cynical man. Cruel, even... Her feeling becomes anxious when she discovers that her host's nephew, Roland, is trapped in the dungeon.

A colossus, the disturbing Piercy, the damned soul of the lord, keeps a watchful eye on the man who is said to be mad... A strange disease destroys the recluse. In charge of treating him, Marguerite swears to clear up the mystery. Little by little, moreover, she feels an irrepressible disorder in her contact with him. His heart is moved, gives itself...

Too late, the two young people will realize the strength of their love and the inextricable trap they have fallen into.

Are they forbidden any hope now?
