Joe, along with other big-cat park owners, is at war with Big Cat Rescue facility operator Carole Baskin, who lobbied to have such parks shut down. As we learn in episode one, Joe is accused of hiring someone to murder her.
Mixing wild animals with humans always ends badly, says Baskin.
The animal rights activist is passionate about wanting to end the private possession of big cats and believes Joe's animal breeding programmes, park conditions and practice of charging people to pet lion or tiger cubs is abusive to the big cats.
She wants to close Joe's park.
This rivalry stirs Joe into issuing violent threats against Carole.
In his many videos, he threatens her with snakes and is seen shooting a blow-up doll with her name on it.
The rivalry comes with a twist and leads to the one of the biggest shocks in the documentary. Joe alleges Carole killed her ex-husband and fed his body to the big cats. No one believes this.
But when Carole's ex-husband's family speak on camera, they say they are scared of Carole and believe she had a part to play in his disappearance.
This resulted in Joe's arrest and later conviction.
“She wanted to shut down the zoo and he wanted her gone,” says Kirkham.
“It's not everyday a zookeeper goes to prison for murder for hire.”
