The ghost of a 1920s teen demands that Marshall deliver a love letter to the spirit's dream girl, now an elderly woman. 

Marshall does not like the Indiana practice of ignoring Daylight Saving Time, and sets his clock back an hour anyway. When he wakes up the next day, he finds himself all alone in another dimension, save for an elderly milkman, a runaway teenage girl, and a group of garbage collectors who want the two of them dead.
