A LONG DAY'S NIGHTMARE - On a quiet spring day in April, realtor Archie Mulgrew is at his open house in Toluca Lake. Just like any other day. He has plenty of potential buyers checking out the property. Susan Marshall is there with her best friend Micah, and Susan's two children - Pace and Mandy. Newlyweds Stephen and Sofia are more interested in checking out each other than the house but that makes for an interesting game of hide and seek with the kids. But before anyone can finish appraising the property...

...Bang! Three criminals, on the run from the police, bust into the house and take everyone hostage. What happens over the course of the next 24 hours is a deadly game of survival, with high stakes drama and a a Stockholm Syndrome-style twist that will surprise even the most frequent movie-goers.
