Seventy-nine-year-old Jack receives a call from a young woman claiming to be his granddaughter, Grace. She tells Grandpa Jack that she's in jail as a result of a car accident and begs him to call her attorney. The attorney claims that Grace was texting and driving and needs money for bail. Jack is instructed to send the money in cash through the mail. Before the ordeal is over, Jack sends $19,000 through the mail — but with the guidance of the police, he's able to fight back against the scammer.
