Holiday at the Seaside

Amalia, a girl of thirteen, gets her first period one day before going to the seaside with her parents. Having a strict and conservative mother, she decides to take care of her "problem" by herself. Little does she know that soon, this will be the smallest problem she has. While struggling with this issue by herself, she doesn't notice that her parents, who discreetly already agreed to split, are on the verge of giving up their last holiday as a family.
