The Happiness Cage

Reese comes to the attention of Major, the head of Army program attempting to help those with terminal illnesses deal with their pain via a brain implant.

Dr. Frederick is trying to find a way to ease the aggressive nature of soldiers by developing a microchip to access the pleasure centers of their brains.

Reese is transferred to the Veterans Hospital in Frankfurt, where the experiments are being conducted by United States Army.

The Army doctors are drilling into the patients’ skulls, attach wires, and alter their brains to create better soldiers and happier men — human robots.
