Midnight Caller is a dramatic NBC television series which ran from 1988 to 1991. It was one of the first television series to address the dramatic possibilities of the then-growing phenomenon of talk radio.

Midnight Caller starred Gary Cole as Jack Killian, a former San Francisco police detective who had quit the force after accidentally shooting his partner to death in a confrontation with armed criminals. After lapsing into alcoholism, Killian receives an offer from Devon King (Wendy Kilbourne), the beautiful and wealthy owner-operator of KJCM-FM, to become "The Nighthawk", host of an overnight talk show, taking calls from listeners and acting as a detective solving their problems during the day.

Killian's adventures took him frequently back into the realm of police work, where several of his former colleagues were less than happy to see him again. He faced a myriad of problems, both personal and professional, and was at various points required to come to grips with the nature of his relationship with both his absentee father and his troubled siblings. What he never seemed to come to grips with, however, was his relationship, or lack of one, with Devon; there seemed to be a lot of unconsummated sexual tension between the pair, especially early in the show's run. Devon eventually became pregnant in a relationship with another man and sold the station (Kilbourne was undergoing a simultaneous real-life pregnancy) and the show never seemed to recover from her absence. Despite hard-hitting topical episodes dealing with AIDS, capital punishment, and child abuse, among other topics, it lost its audience and was soon cancelled.

Jack Killian is an ex-cop in San Francisco. He quit the police force after accidentally shooting his partner. He was approached by Devon King, the manager of a local radio station, and accepted a job as a talk-back host. Ever the humanitarian, Jack (together with his side-kick Billy Po) often gets personally involved with the plight of those who call his show. Written by Murray Chapman
