Detective Della Wilder (Pam Grier) and her partner Harland Lee (Romano Orzari) are tough cops, despite Wilder's penchant for bending the rules. When they're assigned a strangulation case, the main suspect is Dr. Sam Charney (Rutger Hauer), the victim's former lover. While Wilder interrogates him, a second murder occurs, and evidence suggests that it's not the work of a serial killer. Could a big pharmaceutical company be involved?
