The new kid in town is eager to impress the two friends she just made, and tells them wild tales of her four guardians when the latter were hell-raising young women: Stories of murder, bank robberies, and other mayhem.

I think your logline could be improved if you added “stakes” to the storytelling; example
“When a new kid in town reels off facinating tales about her guradians, the impressionable audience report her to the authorities.”
Or something along that theme- add a dimension to the consequences of the stories (maybe the stories are real and give clues to some old, unexplained event in the lives of the towns folk). I’ve no idea what your script is about so I’m just shooting ideas off here…
