This was a very different 2 part Matlock story, both intertwined, a judge puts him as lawyer to a plumber arrested for murder and shorty after that a woman arrested for her husband's death begs him to take her case, and he does and figures out who killed her husband and gets her off.
2nd part, the plumber is not a really likeable guy but they work his case and figure out who might be involved, his client from the first murder, this involves legal issues because of attorney client privilege, but even though she was innocent in her husband's death, she wasn't in this one and actually planted the murder weapon in plumbers Van. Had she not planted the murder weapon on him or anyone else, she might have gotten away with it.
