On their high school graduation day, Andrew gives his twin daughters letters from their late mother, Laura. The revelation inside shatters their world: Laura was not their biological mother.
As Andrew recalls his memories of Laura and their life together, he never imagined the storm coming. After the graduation ceremony, he hands Chloe and Nora the letters from their mother, who admits to having kept the truth about their parentage hidden. The shock and anger are immediate. Chloe accuses Andrew of being deceived all these years, while Nora is devastated, struggling to process the lie.
Tension fills the house as Chloe and Nora barely speak to Andrew. Eventually, Andrew suggests a DNA test, and the results confirm Laura’s secret: he isn’t their biological father. Searching for answers, Andrew finds the man who is—their biological father, Tom, who had no idea they existed.
After a tense meeting with Tom, Chloe and Nora decide to form a relationship with him, but their bond with Andrew remains strong. Despite the revelations, the love and connection they’ve shared with Andrew are unshakeable, showing that family is about love, not blood.
