Gary and Iris are traveling on this one. We have been vaxxed but we are feeling slightly aglow. Could it be radiation? We are back to discuss two films where radiation makes people insanely violent.

Then, a chemical spill causes the inhabitants of an agricultural research lab to become infused with blisters and violent tendencies in Warning Sign.
