A Hero for Our Time (S08E10)

A near-miss on the highway involves Dolly and her daughter Alison, along with a wealthy heir and his girlfriend. Officers Ellis and Ormerod are dispatched to the scene of the incident. To evade the other vehicle, Dolly's car veers off and plunges into a lake. As the car starts to sink, Jack leaps in to rescue them. Meanwhile, the other couple is taken to the hospital for assessment, where a water tank unexpectedly crashes through the ceiling, trapping Tom, the male driver. With a ruptured spleen, Ormerod and Rose manage to free him and rush him to surgery.
