The film opens with a cold flash-forward to November 1943: an intoxicated, disoriented Lorenz Hart falls into a dark Manhattan alley during a torrential downpour, mumbling verses under his breath before succumbing to exposure and fatal pneumonia at age 48.
The narrative then flashes back seven months to the evening of March 31, 1943. Hart arrives at Sardi's early, determined to project total composure. He announces that he has quit drinking and is ready to turn over a new leaf, energized by his infatuation with Elizabeth Weiland. Throughout the evening, he prepares elaborate gestures for her, including parlor card tricks and lavish gifts, trying to convince himself that tonight she will consent to be his partner. When Elizabeth arrives, the emotional dynamic is laid bare. She does not harbor romantic feelings for Hart; while she respects his mind and holds genuine affection for him, she firmly resists his romantic pressure. The heartbreak is understated: Elizabeth loves him as an artist and a friend, but cannot love him in the way he craves.
The second blow lands when Richard Rodgers arrives with Oscar Hammerstein II amidst roaring fanfare. Instead of the fight or triumph Hart fantasized about, Rodgers treats Hart with gentle pity. Rodgers makes it clear that there is no anger left—only a quiet, irreversible finality. Rodgers has built a partnership that provides stability and artistic triumph, leaving no place for Hart’s chaos. Stripped of all remaining illusions, Hart's sobriety collapses. He orders a drink from Eddie, who can no longer refuse him. As the glamorous crowd ascends to the private celebration upstairs, Hart is left down at the bar, nursing his glass. He quietly murmurs the words to "Nobody ever loved me that much" and steps out alone into the New York night, returning the story directly to the fatal rain-soaked alleyway of the prologue.
