In a quiet neighborhood, the life of a single mother, Susan, takes an unexpected turn when her eldest son, Henry, an 11-year-old prodigy, discovers a dark secret about the life of his school friend, Christina. While Susan struggles to cope with her own issues—from a low-paying job to a complicated love life—Henry increasingly becomes the pillar of their family, guiding her with his unusual wisdom.
One day, while investigating the bullying Christina suffers at the hands of her abusive stepfather, Henry decides that he must take action. He devises a meticulous plan and simultaneously starts writing a book that details the instructions for his mother to carry out her mission. Tragedy strikes when Henry suffers a terminal illness, and his ingenious plan falls onto Susan's shoulders. As the mother faces the heartbreak of losing her son and the urgency to fulfill his wishes, she finds herself immersed in a new world of difficult decisions that will lead her to question how far she is willing to go for those she loves.
With a balance of humor and drama, the story explores the depth of family ties, courage in times of crisis, and the fight for justice, reminding us that sometimes the hardest choices are also the most necessary.
