Matt has to go out-of-town so he gets Festus to watch the jail. When Festus finds out that the three men in jail are his cousins, he makes a pack with them. Festus will release his cousin that night as long as they give their 'Haggan Word' that they will leave Dodge and cause no more trouble. They agree and Festus lets them go.
Down at the stables, Mr Halligan is having words with Dave Carson about a mule harness they he felt was not done properly. Halligan shoves Carson and he hits his head on a wagon wheel. In a daze state, Carson stands at just about the time the fir-trappers come to get their horses. Carson falls on on of them and they push him against a door. When they check they find the wound to Carson's head. Thinking they were the ones that injured Carson, they flee town. Mr Halligan tells Festus that it was the fir-trappers that caused Carson's injury
Now with all the fault centered at Festus, he is bound to bring his cousins back to Dodge to stand trial. So Festus sets out on an entertaining journey as he is dead set on catching each family member.
A nice and delightful story that has all the charm of a Haggan family reunion. With backwoods humor and a well seasoned cast, this show was a joy to watch.
