Place—Bohemia.
Act I. At the target range. Kilian, the peasant, has defeated Max, the forester, at a prize shooting, a Schützenfest, maybe. Max, of course, should have won. Being a forester, accustomed to the use of fire-arms, it is disgraceful for him to have been defeated by a mere peasant.
Kilian "rubs it in" by mocking him in song and the men and girls of the village join in the mocking chorus—a clever bit of teasing in music and establishing at the very start the originality in melody, style, and character of the opera.
The hereditary forester, Cuno, is worried over the poor showing Max has made not only on that day, but for some time past. There is to be a "shoot" on the morrow before Prince Ottokar. In order to win the hand in marriage of Agathe, Cuno's daughter, and the eventual succession as hereditary forester, Max must carry off the honours in the competition now so near at hand. He himself is in despair. Life will be worthless to him without Agathe. Yet he seems to have lost all his cunning as a shot.
It is now, when the others have gone, that another forester, Kaspar, a man of dark visage and of morose and forbidding character, approaches him. He hands him his gun, points to an eagle circling far on high, and tells him to fire at it. Max shoots. From its dizzy height the bird falls dead at his feet. It is a wonderful shot. Kaspar explains to him that he has shot with a "free," or charmed bullet; that such bullets always hit what the marksman wills them to; and that if Max will meet him in the Wolf's Glen at midnight, they will mould bullets with one of which, on the morrow, he easily can win Agathe's hand and the hereditary office of forester. Max, to whom victory means all that is dear to him, consents.
Act II. Agathe's room in the head ranger's house. The girl has gloomy forebodings. Even her sprightly relative, Aennchen, is unable to cheer her up. At last Max, whom she has been awaiting, comes. Very soon, however, he says he is obliged to leave, because he has shot a deer in the Wolf's Glen and must go after it. In vain the girls warn him against the locality, which is said to be haunted.
The scene changes to the Wolf's Glen, the haunt of Zamiel the wild huntsman (otherwise the devil) to whom Kaspar has sold himself, and to whom now he plans to turn over Max as a victim, in order to gain for himself a brief respite on earth, his time to Zamiel being up. The younger forester joins him in the Wolf's Glen and together they mould seven magic bullets, six of which go true to the mark. The seventh goes whither Zamiel wills it.
Act III. The first scene again plays in the forester's house. Agathe still is filled with forebodings. She is attired for the test shooting which also will make her Max's bride, if he is successful. Faith dispels her gloom. The bridesmaids enter and wind the bridal garland.
The time arrives for the test shooting. But only the seventh bullet, the one which Zamiel speeds whither he wishes, remains to Max. His others he has used up on the hunt in order to show off before the Prince. Kaspar climbs a tree to watch the proceedings from a safe place of concealment. He expects Max to be Zamiel's victim. Before the whole village and the Prince the test shot is to be made. The Prince points to a flying dove. At that moment Agathe appears accompanied by a Hermit, a holy man. She calls out to Max not to shoot, that she is the dove. But Max already has pulled the trigger. The shot resounds. Agathe falls—but only in a swoon. It is Kaspar who tumbles from the tree and rolls, fatally wounded, on the turf. Zamiel has had no power over Max, for the young forester had not come to the Wolf's Glen of his own free will, but only after being tempted by Kaspar. Therefore Kaspar himself had to be the victim of the seventh bullet. Upon the Hermit's intercession, Max, who has confessed everything, is forgiven by Prince Ottokar, the test shot is abolished and a year's probation substituted for it.
Many people are familiar with music from "Der Freischütz" without being aware that it is from that opera. Several melodies from it have been adapted as hymn tunes, and are often sung in church. In Act I, are Kilian's song and the chorus in which the men and women, young and old, rally Max upon his bad luck. There is an expressive trio for Max, Kaspar, and Cuno, with chorus "O diese Sonne!" (O fateful morrow.) There is a short waltz. Max's solo, "Durch die Wälder, durch die Auen" (Through the forest and o'er the meadows) is a melody of great beauty, and this also can be said of his other solo in the same scene, "Jetzt ist wohl ihr Fenster offen" (Now mayhap her window opens), while the scene comes to a close with gloomy, despairing accents, as Zamiel, unseen of course by Max, hovers, a threatening shadow, in the background. There follows Kaspar's drinking song, forced in its hilariousness and ending in grotesque laughter, Kaspar being the familiar of Zamiel, the wild huntsman. His air ("Triumph! Triumph! Vengeance will succeed") is wholly in keeping with his sinister character.
