Août 1935. Malgré la canicule qui frappe l'Angleterre, la famille Tallis mène une vie insouciante à l'abri dans sa gigantesque demeure victorienne. La jeune Briony a trouvé sa vocation, elle sera romancière. Mais quand du haut de ses treize ans, elle surprend sa sœur aînée Cecilia dans les bras de Robbie, fils de domestique, sa réaction naïve face aux désirs des adultes va provoquer une tragédie et marquer à jamais le destin du jeune homme.
Based on the real story of Tom and Nicola Ray from Rutland. Their perfect life is totally ruined in a single moment after Tom had developed sepsis. While her husband was in coma, Nicola gave birth to their second child on the other side of the same hospital. Within a matter of days, sepsis would rob Tom of both his arms and legs, and left his face severely disfigured. As an ordinary man, Tom never put himself at risk — he just woke up two months later in a nightmare, a face-off quadruple amputee... This incredible story of survival shows what can be overcome when love is unconditional.
