A man was walking his kid to school. In the schoolyard, the kid was bouncing a basketball, when the ball slipped from his hand heading to a dumpster. Among the bins, a dead body was lying on the ground with a couple of bullets in his head. He had no documents with him, but thanks to a key placed in his necklace detectives manage to find out who are the parents of the victim. He's a son of a real estate magnate, but his father has lost contact with him for two years: the victim is actually a junkie, doing a part-time job in a bike shop and he was really angry with his father (as usually happened when brats don't manage to keep up with successful parents). But when a stepsister turns up, he's ready to set his revenge: anyway she's not so foolish as he was and something could have gone wrong.
Great performance for the later detective in Law & Order: Criminal Intent (Jessie Nicholson) who plays the "likely" daughter. I don't understand why this trust fund guys get used to hating their fathers so much after getting everything they wanted in their infancy and boyhood.
