Just the Ten of Us - Season 3 Episode 8 Dangerous Liaison

After a show, a tall-dark-and-handsome stranger buys Wendy a beer and the two go for a joyride. The joy, however, quickly turns to despair when the guy stops at a convenience store -- and robs it. The survaillance tape shows that Wendy didn't have anything to do with the actual robbery, but she doesn't understand why her actions were wrong. So Graham and Elizabeth spend the entire night trying to get through to Wendy that she made bad decisions that had an effect on the outcome of the evening. All the while, Wendy contends that she's innocent.
