Mad Doc’s Experiments (Feather)

A deranged doctor conducts a series of horrific experiments in his underground facility, beginning with a captive girl he tortures with gasoline and fire until her body is drained into the disposal system. He then acquires a new victim from the dark web, subjecting her to gruesome surgical removals of organs while she pleads for mercy, before moving on to Subject No. 3, into whom he inserts parasitic worms that consume her from the inside out. After documenting her death, he initiates a final experiment on an AV actress, using a spiral heating tube to burn her internally, causing catastrophic tissue damage before terminating Subject No. 4.
