The novel follows Jake Barnes, an American expat living in the Parisian café society of the roaring 20s. A wound sustained during the war has left him unable to have sex, and that drives a wedge between him and the woman he loves: Brett Ashley, a twice-divorcée who has embraced the sexual freedom and independence of the age. As they drift through their lives in postwar Paris, they find themselves on a trip with some friends to Spain to witness the Festival of San Fermin, a week-long bacchanal whose highlight is bullfighting.
