Be Careful What You Wish For...

Samantha Byrd is sick of being the unluckiest klutz in school, always being made fun of just because she's tall. However, Samantha has no idea that her life is about to change, starting when she meets an eccentric old woman who claims that she can grant Samantha three wishes. Samantha unkowingly makes her first wish, accidentally exterminating the populace of the planet. However, she has two wishes left, and she'd better make them count, or she could find herself very much alone, for eternity...
