Elena Zavala, 48, is elected Mexico's first female president following a campaign built on anti-corruption and judicial reform. Three seasons track her administration: Season 1 is the first year — the machinery of government, the specific resistance of institutions to reform, the personal cost of the presidency. Season 2 is the political crisis — a cartel escalation that forces Elena to choose between military response and negotiated settlement in ways that divide her coalition. Season 3 is the reckoning — a corruption investigation that reaches people she trusted completely. The romance across all three seasons is with her chief of staff Rodrigo — a twelve-year professional relationship that the presidency finally makes impossible to keep entirely professional.
