The small Scottish animal is in fact his only friend, with the exception of Sarah, their new neighbor, a writer who has decided to settle in the country in search for peace and quiet. One day though, one of the cows catches BSE and, as a result, the whole herd has to be killed.Totally upset, Lucas decides he won't let his friend be put to death. Even if that means addressing the President himself..
