Very specific, yet it's elusive

“There was a movie, tv show, or mini series, about a firefighter who when at a house fire fell over on a table caught fire then ran outside. He got down on the ground outside and his firefighter buddies put him out with blankets and he wasn’t even burned, even though he should have had severe burns. The next day he saved a dog from a drain pipe, then the next day the dog saved its owner from a gas leak, then the next day the owner got on a flight as a flight attendant and saved a man choking as she was the only one who knew the Heimlich maneuver. Throughout all this a reporter followed the chain of bizarre events, even getting onto the plane following the flight attendant, and discovered the identical twin brother from the first event. She reconnected them as they were separated at birth. Strangely both brothers were firefighters and the number of their respective fire stations had similar number.”
