The Furies

Hercules volunteers himself and the boys to take a trunk containing a dowry for the bride of Philemon, son of the wealthy Medios, across the desert to Helios. Pythagoras has a bad feeling about it, increased when his brother Arcas arrives and joins their caravan. Fleeing robbers the party takes shelter in a cave, the home of the Furies, who punish murderers. Seeking revenge for the death of his father Arcas invokes them and they chase the caravan across the desert but when the Furies catch up with the group the killer's identity is unexpected and his fate depends on a test of loyalty and forgiveness.
