Sofía is thirty-five and her husband has left her. Her father died the year before, and her mother is living in the Canary Islands with a new partner. Sofía flees the city with her young son, seeking refuge in her father's house on the southern coast of Spain, where she spent summers as a girl. Her younger sister, with whom she has a close but uneasy relationship, joins her. Living together again, the sisters face their present as well as their childhood and tangled past.

Wolfskin is an intimate meditation on ambivalence and motherhood, eroticism and disappointment, family violence and failure, and ultimately, the possibility—or impossibility—of living with those you love.
