Gladiators 7 (1962)

Falsely accused of aiding the escape of five gladiators from the blood-soaked arena, a noble son of Sparta finds himself enslaved, thrust into the brutal world of the Roman Colosseum as a gladiator. Fighting not only for survival but also for honor, he endures years in this gladiatorial purgatory, only to eventually orchestrate his daring escape. On his return to Sparta, he is beset by tragedy—his father, a distinguished citizen, has been unjustly slain, his death conveniently declared a 'suicide'. The woman he cherishes is betrothed to a malevolent king who has seized the throne through treachery. Fueled by a burning desire for justice and revenge, he embarks on a quest to reunite with six of his gladiator brethren. His mission: to rescue his beloved, overthrow the corrupt king, and restore the throne to its rightful ruler.
