A doctor becomes suspicious when a surprisingly high number of patients at her hospital end up in comas, and are shipped off to a mysterious institute. Convinced something sinister is going on, she investigates further, only to uncover a frightening secret that places her own life in danger.
"In this taut medical thriller, faithfully adapted from Robin Cook's bestseller by doctor-turned-novelist Michael Crichton, Geneviève Bujold's medic suspects foul play when patients start dying unexpectedly in her hospital. The ER/Jurassic Park creator also directs and expertly turns the suspense screws in the gripping way that has become his trademark. It's Crichton's assured sense of creepy paranoia within the absorbing central mystery that gives an extra disturbing edge to the hospital horrors." - Radio Times Review
