The Fugitive - Season 2 Episode 3 Man on a String

While walking on the road late at night, Kimble comes to the aid of Lucey Russell after her car has broken down. As a gratitude, she provides him her place to stay for the night. But the next morning, the police find the dead body of Lars Adams (a married man who Lucey has been having an affair with) only a few feet where her car broke down. As a result, Lucey is arrested for Lars' murder. Lars' wife, Amy, realizes that her husband was killed accidentally, but after learning of his philandering with Lucey, Amy decides that Lucey should take the rap. Kimble realizes that he can prove Lucey's innocence, but testifying for her could jeopardize his own freedom.
