As the fog rolls in, you attempt to call your brother to let him know you'd be arriving late. However, a simple misdial of one digit directs your phone call to someone you don't know.

Wrong number. No big deal, right?

That is, until the mysterious woman on the other end holds your call hostage with a series of nonsensical questions.
