Elisabeth is extremely collected and organized. Briony is scattered and creative. They’re different as day and night, yet they become best friends. What unites them is that family means a huge value to each of them. Safety and children’s health come first. However, without knowing it, they radically disagree on one very important question: should vaccinations be done or not? And what if the decision you make becomes a mistake and harms your child? Afraid of her friend’s judgment, Briony hides certain circumstances from her—hoping… no, being sure that nothing terrible will happen. But it turns out differently, and what seemed like an innocent lie leads to catastrophe.
