Teresa's home is the focal point where her four daughters and her mother-in-law, a 90-year-old woman with senile dementia who lives under her care, converge. The daughters join their mother and grandmother at a family gathering to commemorate the anniversary of their father's passing. The different personalities of the sisters (the nurturer, the rebellious, the wild, the adventurous and yet absent) will trigger multiple conflicts, which will cause the protagonists to clash with each other while dealing with their own frustrations, fears and longings.
Verano en diciembre is produced by Vértigo Films -which also distributes- and Mare Films, with the support of RTVE, Movistar and ICAA.
