Architect Gene López-Pérez has everything she's ever wanted: her daughter Susana, a flourishing career, and Isa—the love of her life and Susana's biological mother. But when Gene is denied entry to a hospital emergency room because Susana is not biologically hers, the harsh reality of her situation begins to sink in.

Meanwhile, Isa, a trailblazing biomedical engineer, juggles her hidden family life and a career threatened by homophobia in a male-dominated field. She doesn't dare risk losing the funding for the important medical research that she's doing.

When Spain legalizes same-sex marriage, Gene proposes a bold solution—move to Spain, marry, and secure the parental rights she's never known. But Isa's refusal sparks a rift, pushing Gene to a daring decision for her family's future.

As Gene contemplates a groundbreaking legal battle for parental rights in Florida, and Isa's career teeters on the edge, their love faces the ultimate test. Can they bridge the divide between them, or will their dreams and duties force them apart?
