After working together on Octavius's uncle's farm, friends Octavius and Demetrius go to sleep. Octavius dreams of having sex with Demetrius.

Roman soldiers wake them and kidnap Octavius because Octavius's uncle can't afford to pay taxes to Rome. The soldiers tell Demetrius to bring a pouch of silver the next day to pay the taxes and free Octavius.

That night, the soldiers' commander admires Octavius's beauty and commands the soldiers to rape Octavius.

While the soldiers are sleeping, Demetrius arrives to rescue Octavius. Sending Octavius out, Demetrius considers killing the commander but decides against it. As the friends run away, Octavius escapes, but Demetrius is captured.

The soldiers and their commander taunt Demetrius, saying he will be sold as a slave. At the slave market, Demetrius is sold to the emperor of Rome.

Before being transferred to the emperor, Demetrius is held in a dungeon where soldiers and other slaves rape him to train him to be submissive for the emperor.

Octavius brings the pouch of silver to the commander to pay the taxes and free Demetrius. However, the commander says the money isn't enough and rapes Octavius.
