Jack investigates an accident where Byrony Darrow was hit by a car while walking home. In a coma and unlikely to recover, Jack starts looking into her background. Her husband was at home with their daughter when the accident happened but there is evidence of sexual activity and Frost suspects that she may have been having an affair. What he learns about her shows that she had a far more complex life than anyone imagined. Separately, Jack investigates a robbery at a local brewery. Jack describes the robbery as "OTT" - over the top - since the thieves wore ski masks and used a sawed off shotgun when there was only one elderly security guard on duty. Using information from the police archives, he manages to lay a trap for the would-be thieves.
