Tabitha, once the placid, gentle and devoted pet, adopts all the characteristics of a ferocious, wild animal following the murder of her mistress. The three guilty people are all trapped by the cat's power and each will come to untimely deaths of horrific proportions without anyone being able to solve the mystery that surrounds their brutal death.
Unfortunately the movie The Shadow of the Cat is not yet available on HBO Max.
