Six-year-old Sam is heartbroken after the loss of his mother and struggles to understand why she hasn’t returned, even though his father told him she “flew to heaven.” In his confusion, Sam calls 911, hoping someone can help bring her back.
Officer John Lewis gently suggests that Sam write his mother a letter and send it with a red balloon so she can find her way. Taking the advice to heart, Sam begins writing letters every month, sending them off with red balloons, though he never receives a reply.
