Set in the bustling, sun‑kissed city of Valencia, the series follows the tangled lives of three women whose fates collide in the most unexpected way: a 24‑year‑old newly‑wed, her 42‑year‑old sister‑in‑law, and the sister’s own partner, a charismatic entrepreneur who’s just moved back from a stint in Berlin. A seemingly innocuous “sister swap”—a weekend getaway where each pair pretends to be the other for a “cultural immersion” experience—spirals into a series of hilarious misunderstandings, heartfelt confessions, and ultimately, a redefinition of what family really means.
