Night Heat was a Canadian police drama series, which aired on both CTV in Canada and CBS in the United States. Original episodes were broadcast from 1985 to 1989 in the United States, and until 1990 in Canada. Night Heat was the first Canadian-produced drama series to air on an American network. CBS aired the series as part of CBS Late Night, a late night block of drama programming. Despite its late hour, Night Heat received good ratings for CBS, sometimes even beating NBC's Johnny Carson Show. After it was canceled, reruns continued to air on CBS for another two years, and on Canadian TV well into the early 2000s. Night Heat reruns were available on Showcase, TVtropolis and DejaView.
The show starred Allan Royal as journalist Tom Kirkwood, who chronicled the nightly police beat of detectives Kevin O'Brien (Scott Hylands) and Frank Giambone (Jeff Wincott). For Hylands, a 21-year veteran actor, frequently seen playing villains in U.S. TV shows during the 1970s and early 1980s, this was the first time he had been given a leading role, or the role of a "good guy." The Kevin O'Brien character was described as "a somewhat cynical, hardened hero." The cast also included Susan Hogan, Wendy Crewson, Sean McCann, Louise Vallance, Stephen Mendel, Eugene Clark, and Clark Johnson. Concurrent with her work on Night Heat, Vallance was starring in the children's series Zoobilee Zoo.
