We revisit Dr. Pol and his son Charles as they must solve a mystery -- 10 Angus steers have suddenly gone lame and are struggling to stand. A steer's kick can be lethal, and to treat the sick cattle Dr. Pol will have to stand directly in harm's way. Back at the clinic, we see a recent widow who is prepared to pay whatever it costs to save her late husband's dog after the pet swallowed a rock. The sweltering heat isn't the only thing causing Dr. Pol to sweat; he's preparing for a family reunion.
