A young couple has a chance to move into a gorgeous duplex in the perfect New York neighborhood. All they have to do is bump off the current tenant, a cute little old lady.
 
No review.  Just a quote from the movie.
 
Nancy Kendricks: [Mrs. Connelly leaves to run errands] Okay, come on. We don't have that much time.
Alex Rose: I know. She's running errands. That only gives us twelve hours.
 
Nuff said.
 
FUN FACT:  When Alex and Mrs. Connelly are having the clap on clap off war as Alex puts up the middle finger towards the ceiling you can see Drew Barrymore's character Nancy put her face into her pillow to keep from laughing.
