Where can I watch Fierce Creatures in United States?

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.
