Young Alec Ramsay is shipwrecked on a desert island with a horse destined to play an important part in his life. Following their rescue their adventure continues in America.

The Black Stallion's son arrives from Arabia and young Alec is ecstatic, but his trainer, Henry, sees a killer's instincts.

When the Black is returned to Alec Ramsey, the whole racing world, including Alec himself, wonders which horse is faster: the great stallion or his son, Satan.

When his wild black stallion revolts against the routine and schedule of stable life, becoming a killer and a threat, a plane crash thwarts Alec's plans to give the Black a free run in the desert and brings danger to both boy and horse.

The arrival of three strikingly handsome colts in the U.S. leads Alec Ramsey to believe that the sire of his world-famous black stallion is still alive.

While flying to a race, Alec Ramsay and the Black's plane crash-lands in the stormy Caribbean. Chance brings the Black to the hidden island home of the giant red stallion, Flame. Such a small island can only support one alpha male. But before the two can fight -- a fight that can only result in the death of one -- a new danger appears. Together, can the stallions defeat the deadly foe which threatens the lives of the entire herd of wild horses --...

While riding the Black in the Everglades one day, Alec meets a mysterious man astride a striking gray mare. Invited to the stranger's home, Alec is fascinated but uneasy... a feeling that grows as he realizes the man is dangerously close to insanity. Soon Alec and the Black are caught up in a deadly chase through the depths of the Everglades, where a misstep could be fatal.
