Overview Construction:
The setting is 1931, a period defined by the Great Depression, which stands in stark contrast to the preceding Roaring Twenties. As the era of Prohibition approaches its conclusion, the narrative focus shifts toward the changing landscape of the country. Enoch Nucky Thompson, who serves as the treasurer of Atlantic City and operates as both a politician and a gangster, seeks to navigate these shifting circumstances. In an effort to legitimize himself, Nucky looks to forge new alliances with various liquor producers. This transition occurs as the rules that once governed Atlantic City at the dawn of Prohibition are being challenged by the economic realities of the 1930s. The season explores Nucky's attempts to adapt his influence and status within a nation undergoing significant social and economic upheaval. (Word count check: ~135 words.
