Torture Tunnel (Silvio Dante)

In 900 A.D., a sadistic Proctor tortures captives in a brutal inquisitorial dungeon, while in the present, Carlo Ferrari uses an untested time-travel device to bring his wife Francesca and assistant Olivia to the 10th century for thrills. They materialize in the dungeon, where guards seize them, and Francesca and Olivia endure relentless graphic torture, including branding, violation with devices, and a spiked iron coffin, as Carlo anxiously waits at the time tunnel entrance. The time-travel mission concludes with one woman left stranded in the dungeon, while Carlo discovers his wife Francesca has been severely maimed by her captors.
