When the remains of a local chicken farmer are found mutilated by a nearby river, Booth and Brennan investigate the various suspects, including several animal rights activists who are protesting outside the chicken factory. Angela, feeling bothered by the practices of the chicken farm, asks for donations to save a piglet in which Brennan declines as her belief of saving one will not change anything, causing her to question why they are friends. After Wendell makes a donation to Angela, they kiss and a relationship starts to develop as Angela has now been celibate for five and half months.
