The high-priest of the heathen god Dagon finding his friend slain, vows to be avenged upon the Israelites, but he is deserted by all his companions who flee before Samson's wrath.
In the next scene the Israelites return victorious and are greeted with triumphant songs and offerings of flowers. Even the Philistine Delila, the rose of Sharon receives them with her maidens, and pays homage to the hero Samson.
Delila had enthralled him once before, and again her beauty causes him very nearly to forget his people and his duty; but an aged Israelite implores him not to listen any more to the arts and wiles of the enchantress.
In the second Act Delila has an interview with the high-priest, whom she promises to avenge her people by winning Samson's love once more.
She proudly refuses the reward which the high-priest offers her, for it is her bitter hatred against the hero, who once loved and then forsook her, which prompts her to ruin him and to force from him by every means in her power the secret of his strength.
When the high-priest has left her, Samson comes down the steep mountain path, drawn to Delila's house against his will. She receives him with the greatest tenderness, and once more her beauty and her tears assert their power over him, so that he sinks at her feet and falters out his love for her. But in vain she tries to lure his secret from him. At last she leaves with words of contempt and scorn and enters the house. This proves his undoing. Goaded beyond earthly power he rushes after her and seals his fate. After a while the Philistines surround the house and Delila herself delivers her unfortunate lover, whom she has deprived of his strength by cutting off his locks, into the hands of his foes.—
In the third Act we find Samson in prison. Bereft of his eye-sight he has to turn the heavy mill. From the outside the wailings and reproaches of his Israelite brethren are heard, who have again been subjugated by their foes. Bitterly repentant Samson implores God to take his life as the price of his people's deliverance.
In the last scene he is led away to Dagon's temple there to be present at the festival of the Philistines, celebrated with great pomp in honour of their victory.
On the conclusion, after an exquisite ballet, Delila presents a golden cup to the blind hero, and insults and jeers at him for having been fool enough to believe in her love for him, the enemy of her country. Samson maintains silence, but when they order him to sacrifice at Dagon's shrine, he whispers to the child, who is guiding him, to lead him to the pillars of the temple.
This being done he loudly invokes the God of Israel, and seizing the pillars tears them down with mighty crash, burying the Philistines under the ruins of the temple.
