Creatures of the night find new prey on the scariest night of the year in this horror story. It's Halloween night, and four friends -- Allison (Vanessa Horneff), Elliott (Wil Horneff), Trevor (Karl Jacob), and Brian (Sean Reid) -- are on a road trip en route to a friend's wedding when their car breaks down after running into something. Looking for help, the four happen upon the farmhouse of an elderly couple, Elvin (Richard Little) and May (Barbara Wilhide), which is located next to a huge barn. Elvin and May have already become lost in the darkness of the barn, and soon two of the lost travelers are suffering the same fate as they search for friendly strangers. However, while they can barely see a hand in front of their face, they discover they're not alone in the barn, which has become home to a huge swarm of bloodthirsty bats. The Roost is framed by an introduction and postscript from a television horror show host, played by Tom Noonan.
