Hedda Gabler, the degenerate daughter of a drunken, dueling father, has just returned with her husband, George Tesman, from their honeymoon. Hedda, who possesses an uncanny affection for her father's pistols, lives in jealous watchfulness over Ejlert Lovberg, a former lover whom she often pictures in Tesman's place, in her imagination. Lovberg, while under the positive influence of Thea Elvsted, has written an important book, and Hedda, learning this, sets out to recapture Lovberg's affection, whereupon he takes to drinking, loses the manuscript, and is cast into despair. Tesman finds the manuscript, which Hedda then obtains from him. Lovberg then breaks with Thea and goes to Hedda. She shows him her pistols; he takes one and goes to Thea's home where, in her arms, he shoots himself. Hedda, after burning the manuscript that she regards as the child of Lovberg and Thea, shoots herself as well.
