Fangs (2002)

Scottsville is a sleepy town, where the only "memorable" event is the yearly apple-blossom festival, so Police Chief Sam Taylor is furious when Ally Parks, a young cop from the big city, insists on investigating the death and mutilation of Prof. Fuller, who experimented on bats, and soon several other victims, as unnatural bat attacks. She finds a helpful "expert" in animal controller Dr. John Winslow, and the couple gets help from his inquisitive daughter Genny and her practically live-in high-school friend Logan to unravel how it all ties in with real-estate mogul Carl Hart's dishonest and corrupt practices.
