In a Texas suburb, a typical lottery scam has turned into something much more sinister. A scammer has promised a retired couple a fictitious lottery payout if they continue to send him money for fees and taxes. With their life savings gone, the victims are forced to sell their home. But the swindler isn't done with them yet, as his constant calls have created a bond between him and the 70-year-old woman, who may be suffering from dementia. He realizes that she has grown fond of him and pivots from a lottery to a romance scam. He promises her a beautiful life together on the sandy beaches of Jamaica, where he's based. The con man tells her that all he needs is money in order to start building an oceanfront dream home that they can share. To come up with the funds, he proposes a disturbing plan. He demands that she kill her husband and flee to Jamaica with the proceeds of their home sale. The U.S. Postal Inspection Service, which has been monitoring a trail of cash making its way from the U.S. to the scammer in Jamaica, discovers the couple in Texas and sends an agent to their home. When the agent arrives, little does he know he's about to walk into a murder plot.
