Set in two contrasting environments that undeline the same premise of imprisonment, Selda tells the story of Rommel (Sid Lucero), a young man who accidentally kills a boy, resulting in his incarceration. Inside the jail, he befriends another inmate, Esteban (Emilio), who becomes his rock and protector. Seven years later, Rommel is living in the province as a farmer together with Sita (Ara Mina) his wife. Esteban tracks down Rommel in hopes of renewing a brewing love affair. Rommel and Sita welcome Esteban into their lives, until their intimacy crosses borderlines and results in the undeniable scourge of self-discovery.
