Kolchak faces another Native American monster, this one known as the Matchemonedo, when he learns of a series of mishaps taking place in a newly opened hospital. The construction of the hospital has awakened Matchemonedo, an invisible manifestation that causes ruptures in the building's constitution, electrical outbursts, and deaths that are seemingly caused by electrocution. Kolchak enlists the help of a reluctant Indian shaman to combat the rampaging force. Written by acidxian

The Matchemondeo
10 November 2014 | by (North America) – See all my reviews

Carl Kolchak(Darren McGavin) investigates the mysterious deaths and strange occurrences surrounding the construction and opening of a new lake-front hospital, which turn out to be the result of the awakened spirit of a Native American god named the Matchemondeo, who is angry that his roaming/resting place has been disturbed, and will stop at nothing to destroy the hospital by all means at its disposal. Only with the help of a local Indian shaman(played nicely by William Smith) can Carl defeat/placate this threat. Another far-fetched premise helped by the usual effective humor of the series, and a genuine sense of menace posed by the title entity.
