Star Trek Deep Space Nine - Day of Honor - Honor Bound

The hunter instinct is taking over Alexander, driving him to violence when he can't control his emerging Klingon traits. He's in trouble at school when his father, Worf, gives his word as a Starfleet officer that Alexander's behavior will change. It takes a frightening confession from Worf before Alexander understands that he must learn to control himself or lose everything he loves. A Klingon is honor-bound to keep his word, at any cost.
