Ex-policeman Rollo Lee is sent to run Marwood Zoo, the newly acquired business of a New Zealand tycoon. In order to meet high profit targets and keep the zoo open, Rollo enforces a new 'fierce creatures' policy, whereby only the most impressive and dangerous animals are allowed to remain in the zoo. However, the keepers are less enthusiastic about complying with these demands.
Unfortunately the movie Fierce Creatures is not yet available on HBO Max.
