Uncaged (2014)

Suspended-cop John Dakota just wanted a nice day out at the zoo with his kid. Unfortunately, an international diamond smuggler, a group of violent mercenaries, and a swath of wild animals are about to collide and Dakota is caught in the middle.
If you love the violence and mayhem of 80s and 90s action films, you need to read UNCAGED. It'll wrap you in a warm blanket of blood, bullets, and death.
