A novice knight and his unlikely allies lead a crusade against evil in this adventure set in 12th century France. Robert Nerra (Eric Stoltz) is a young knight who, after the death of his older brother, abandons the struggle to defend his father's property in a skirmish over land rights and instead sets out to offer his services to King Richard the Lionhearted. As Nerra makes his way through a France racked with poverty and sickness, he encounters a group of orphans who are trying to flee from the Black Prince (Gabriel Byrne), a dark-clad rogue knight who steals children and sells them to Arab slave merchants. At first thinking him to be King Richard himself, the children follow Nerra, and he tries to protect and organize them as best he can. As they march through France, the orphans' numbers grow, and soon Nerra finds himself leading a crusade of children as he at once leads them to safety and fights off the Black Prince's forces. Lionheart was one of the final films from veteran director Franklin J. Schaffner; the film received an unfortunately short-lived theatrical release and went largely unseen until it was released on home video in 1990, a year after Schaffner's death.
