Dwayne Johnson is "goin' primal" in Georgia.

The wrestler-turned-actor is busy working on the Warner Bros. action flick "Rampage," and apparently getting ready to shoot put him in the sharing mood. Until now, little was known about the film's storyline, but that changed this weekend. Johnson revealed a more detailed description of his role and the plot in a new Instagram post.

The movie sounds kind of like a cross between "King Kong," "Jurassic World," and even "Monkey Trouble." In it, Johnson's character is the head of an anti-poaching unit in Rwanda, and he gets mad when some bad people infect his best friend -- a gorilla named George -- and other animals with a serum that makes them grow quickly and become aggressive. The result is a rampage that actually puts the world at risk, so Johnson's character decides to hunt down the people responsible.

Goin' primal. ???? Good to finally have boots on the ground here in Georgia for production of #RAMPAGE. I head up an anti poaching unit out of Rwanda. My best friend is a rare albino gorilla named, George. Very bad people infect George, an alligator and a wolf with a serum. All three animals grow at an unprecedented rate. Their size, speed, agility and violent aggression is off the charts. They go on a deadly rampage and want to destroy the world. George not happy. Me not happy. When animals like you, they lick you. When they don't like you, they kill you. I will hunt down the bad people who did this to my best friend. And when I find them, I will not lick them. We have the best VFX monster making team (WETA) on the planet. Our actors and crew have been working very hard to raise the monster genre bar. As always, let's have some fun. Let's shoot. ???????? #PrimalDNA #George #Lizzy #Ralph #RAMPAGE
