If monsters don't exist, why is everyone in this town obsessed with yowies?

All Jacinta wants is to go back home to Sydney, but her mum must solve a case first: a missing person with no clues, unless you count eyewitnesses who saw him get eaten by a yowie. But monsters aren't real, so what's really going on?

When the police struggle to find new leads, Jacinta launches her own investigation and quickly learns giant hairy monsters might actually exist. She befriends Cory, a local yowie expert, and the two hunt for their monster. When Cory's desperate search for the yowie becomes dangerous, will Jacinta find her yowie or be its next victim?
