The Stripper - S1-E3
Stupidity: The whole plot resolution can happen merely because, on top of Matlock's unbelievable guess on how to trigger someone's dormant personality - apparently murder wasn't enough, but a joke is - the transvestite has two entirely separate voices, one of which is a dubbed-in female one. Not quite believable even for the times.
Stupidity: The gas station attendant can (at least hypothetically, he turns out to be wrong) recognise someone who did a hit-and-run a long distance away at night, but somehow he does not recognise in court the client of the station who was with him at the same time and interacted with him for a few minutes.
Stupidity: As far-fetched as Matlock's stunts can be in most episodes, in this one you have one of the most egregious examples of something that would never stand. Here, The Witness confesses to murder under the direct threat of an attack dog that Matlock practically sic[s] on him, and nobody bats an eyelid about it. On top of that, the culprit and his associates are all legal scholars, as the episode itself more than once reminds the viewer.
Answer: Leanne often went to the beach whenever she was upset about something. In this episode, Leanne realised that Kevin, the guy she had been seeing, had broken into her home and taken her diary in hopes of learning everything about her. This upset her because her privacy had been invaded and Kevin thought that the entries in her diary described the kind of man she was looking for. Ben drove down to the beach to comfort Leanne.
Only problem with that is that earlier in the episode LeeAnn went for a jog on the beach. She drives three hours to jog?
She didn't go for a jog. She went there because she was upset.
