Long Day's Journey into Night

The play takes place on a single day in August 1912. The setting is Monte Cristo Cottage, the seaside home of the Tyrones in Connecticut. The four main characters are the semi-autobiographical representations of O'Neill, his older brother, and their parents, including his father actor James O'Neill.

The play portrays a family struggling to grapple with the realities and consequences of each member's failings. The parents and two sons blame and resent each other for various reasons; bitterness and jealousy serve as proxies for ultimately failed attempts at tenderness and compassion. The family's enduring emotional and psychological stress is fueled by their shared self-analysis, combined with articulate honesty. The story deals with addiction, unfulfilled dreams, moral flaws, and the struggle of family relationships.
