New Orleans District Attorney Jim Garrison discovers there's more to the Kennedy assassination than the official story.

After the first massacre in 1974, the townspeople suspected that the Sawyer family were responsible. A vigilante mob of enraged locals surrounded the Sawyer house, burning it to the ground and killing every last member of the family. Decades later, a young woman named Heather learns that she has inherited a Texas estate from her grandmother. She decides to bring her friends along on the road trip to investigate her inheritance. On arrival, she discovers she has inherited a mansion, but is yet to uncover the terrors that lurk in the basement underneath it.

Five friends head out to rural Texas to visit the grave of a grandfather. On the way they stumble across what appears to be a deserted house, only to discover something sinister within. Something armed with a chainsaw.
