At the Scientific Research Institute for the study of Homicidal Baked Goods, The Gingerdead Man is visited by a woman from the FBI (Laura Kachergus), who is revealed to be the sister of Toothless McHomeless of Gingerdead Man 2: Passion of the Crust, who was driven to suicide by the previous Gingerdead cookie. As she's about to take her revenge on this "half baked piece of shit", a group of activists for animal rights break into the institute, overpower her, and release the Gingerdead Man and the rest of the baked inmates. The killer cookie comes across the "Time Travel Studies" room, shoots the two scientists, and is sent back through time as security tries to kill him.
