Mary is having nightmares and sleepwalking. Her parents believe her problems are due to her obsession with horror movies and make her promise she will not watch any more horror. But Mary and her friends decide to go see the new movie, The Wisher.
When Mary's dad finds out, he heads down to the theater to bring her home, but is killed in a car accident. Mary believes this is her fault as she wished he was gone from her life forever. She also finds that other wishes she makes are coming true and thinks it must be the villain from the movie.
The stupid thing is that in order to prove her theory that the Wisher is making her wishes come true, she gets in her friend's car and wishes that they would crash. But instead of letting things go normally and seeing if it happens, they start driving a hundred miles an hour through back alleys.
Who wouldn't crash at some point?
The movie also features Drew Lachey as Brad, Mary's love interest who she comes to suspect is The Wisher.
