On the life of my sister

Sara and Brian Fitzgerald have a son and a daughter. Their carefree life takes a tragic turn when they learn that two-year-old Kate has leukemia. The parents now hope to have another child who could save Kate's life. For the Fitzgeralds, especially for Sara, there is no choice: they will do whatever it takes to keep Kate alive. In this case, that means Anna. Kate and Anna are closer than sisters usually are: although Kate is the older one, her life completely depends on Anna. Despite their young age, the sisters must endure numerous medical procedures and hospital stays - this has become part of the family's daily routine, as they stand together firmly in every situation. The loving wife and mother Sara has given up her career as a lawyer to be there for her daughter - sometimes she becomes desperate at the unwavering commitment with which she fights for Kate's life. Her solid husband Brian supports her in every way, but his wife's willpower even condemns him to passivity. Their son Jesse feels neglected because Kate and Anna are constantly in the spotlight. But one day, eleven-year-old Anna says "no." To assert her medical independence, she hires a lawyer to take her case to court. The family is divided - and Kate's fragile health is left to fate.
