I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Dying Breed Movie plot: Tasmania, 1800s. Alexander Pearce, a convict known as "the Pieman", has escaped into the wilderness and he is being hunted by policemen with dogs. He is faced by a policeman who attempts to shoot Pearce, but his gun does not fire. Pearce then bites the policeman's neck, taking a large chunk from his throat, killing him, allowing Pearce to escape. Present Day. Nina plans a trip with her boyfriend Matt to Tasmania to find the supposedly extinct Tasmanian tiger. Her endeavor is encouraged by a paw print that was discovered by her older sister in a remote area of the island before her body was mysteriously found in the Pieman River several years before. Matt's friend, Jack, and his girlfriend, Rebecca, help pay for the trip and accompany the fellow couple. When they arrive, Matt sees a small girl on the boat playing a game with yellow-tinted teeth. When Matt asks what she is doing, she recites a rhyme, but Matt gets too close and then she bites his hand, causing it to bleed. They spend a night in a dingy motel located next to a meat-pie factory, meeting the eccentric and creepy locals. The next day, the group goes out on a boat in the river along the forest. They decide to camp in a cave out in the woods, and later that evening Matt and Nina discover one of the Tasmanian tigers creeping through the bush. Nina rushes to get her camera to take a picture of the tiger, but it has run into the woods. The group goes into the dark after the tiger using their cell phones as light because capturing proof of its existence is critical to Nina's research. Unbeknownst to the rest of the group, Rebecca is captured and eaten by a cannibal. When the other three re-group, they realize that Rebecca is missing and that Nina has blood on her pant legs. Desperate to find Rebecca, the group searches through the forest. The local ferryman tries to help them but is murdered by one of the cannibals. Reaching an old mining site, they find Rebecca's remains strung up on meat-hooks and Jack is killed by an animal trap. Matt flees... My question: Modern science refuses to believe that what Australian animal still exists?
