Atlantic City, 1922: The Roaring '20s are about to begin in earnest and despite a booming economy, alcohol is scarce and gangster violence is heating up. Amidst this backdrop, Nucky Thompson (Steve Buscemi), whose marriage to Margaret has become a sham after she signed away his highway windfall to the church, faces the challenge of mending old relationships. Nucky also encounters new competition from a hair-trigger gangster who builds a strategic bulkhead between New York and Atlantic City in an effort to siphon off Nucky's alcohol business. The conflict brings out the best and worst in Nucky as new and familiar faces undergo compelling metamorphoses within the third season of this Golden Globe and Emmy Award-winning series.
