Plot summary
A female food critic Sally Moore ( Moira Driscoll ) is found beaten to death. Goren and Eames suspect the chef at the last restaurant she visited, run by upcoming chef Joshua Mailer ( Alex Burns ). However, Joshua has gone missing and their investigation turns to his father-in-law Tommy Onerato ( Chris Penn ), the owner and head chef of a popular upmarket restaurant. Joshua's beloved motorcycle is found dumped on the beach suggesting suicide, however Goren and Eames learn suspect foul play. Further investigation of Tommy, his restaurant, his bullying behavior and strained relationship with his daughter, Beatrice ( Monica Keena ), leads the detectives to believe that he has had a long-term incestuous relationship with her.
They accuse Tommy of killing Sally Moore to frame Joshua and then killing him and cutting up his body, prompting Beatrice into revealing she has evidence of her father's actions and enabling the detectives to charge him with the two murders.
