Solarium-3

Nobody's talking. But something has gone terribly wrong. Seven researchers are sealed inside Solarium-3, a huge self-sustaining science complex, to see if life can survive in a completely closed, man-made environment. But after a few weeks, something goes wrong. Their air inside turns foul and will quickly become fatal. Frantic attempts to solve the problem fail. Desperate, they beg Project Control to release them. Control says no - but won't say why. Then comes the horrifying truth.
