To celebrate Gerry's birthday, Emily takes her reluctant father and the team to a comedy club. However, one of the acts causes trouble -- racist, sexist, and homophobic comedian Ray Harris is not everyone's idea of humor.
Gerry's enjoyment is certainly at odds with a group of hecklers, who cause such a commotion that they are manhandled out of the show. Somewhat affronted by their treatment, Pullman intervenes and discovers that the most vocal of the hecklers, Jo, is the niece of a political activist, Sarah Jones, who went missing with her boyfriend 25 years ago after waging a campaign against Harris and his act. Warming to the feisty Jo, Pullman agrees to reinvestigate Sarah's disappearance.
