Blood Sport premiered as a 2-hour installment of the syndicated TV anthology "Mystery Wheel of Adventure." It was one of three Irish/Canadian productions based on the works of mystery writer Dick Francis. As in the other Francis mysteries, Ian McShane stars as British Jockey Club investigator David Cleveland. His assignment: to locate a missing race horse, upon which the fortunes of several people (nice and otherwise) are pinned. Kenneth Welsh costars in this made-for-TV puzzler.
