Plot
After closing hours in the Starbody Health Spa in Los Angeles, Laura Danvers is mysteriously locked inside the sauna, which fills with chlorine gas, inducing chemical burns on her skin and eyes, nearly killing her. Her boyfriend Michael Evans—the club owner whose wife Catherine committed suicide the previous year—is notified and rushes to the hospital. The club features a state-of-the-art computer system which controls its various workout machines and other features, and is managed by David, Catherine's twin brother.
