Sister Kate is transferred from an archaeological dig to an orphanage known as Redemption House and finds herself in charge of seven orphans: three teens (Todd, April, and Frederika), two pre-teens (Hilary and Eugene), and two youngsters (Violet and Neville).

The nun and the children take to each other like oil and water: she prefers her own company and takes no guff, while the children are rough on authority figures and have previously driven off three priests who attempted to tame them. However, Sister Kate’s gruff charm eventually wins the kids over and heartwarming moral lessons are learned by all.

The show ran from September 1989 to January 1990, then returned for one month in June of that year. Only 19 episodes of Sister Kate were produced.
