My Brother's Secret

An adoptive mother seeks money from daughter Iris for her disabled son's marriage. Iris scorns her, refusing due to resentment: her mother hid Iris's University Acceptance Letter, leading her brother to sacrifice his education for Iris, becoming disabled. The truth emerges: her brother is the anonymous benefactor Iris sought. Iris learns her origins (she is adopted, brother abandoned baby), feels guilt, and reconciles with her sacrificing brother.
