What is the Plot of Sister Boniface Mysteries Season 4?
In the season’s extended Christmas special, Sister Boniface becomes embroiled in a panto fiasco when the Great Slaughter Amateur Dramatic Society puts on its version of Cinderella. Guided by a celebrity director, the panto soon turns to chaos as cast members die off one by one, Sister Reginald realizes that the turkey he was sent to fatten has gone missing, and a cat even delivers a human eye. Sister Boniface is on the case to find the killer and save the show and the holiday spirit.
The main series provides a flurry of odd, cozy mysteries in 1960s Great Slaughter: a runaway bronco in a game show set that sends a local farmer flying, a village haunted by a terrifying scarecrow, a dreadful stunt involving a femme fatale that ends with her dead, and much more pandemonium caused by a failed “team-building” exercise orchestrated by Chief Constable Lowsley instead of cohesion. Meanwhile, Reverend Mother Adrian has a secret that could put convent life as she knows it in jeopardy.
