Brian Mertes (David Greenspan's The Myopia) directs the Rattlestick production of Rivera's play that has been reconceived since its 2007 world premiere. The Rattlestick bills it as a new, world-premiere production of the dark play.

According to the Rattlestick, "In a small New Hampshire town, seven friends conspire to murder their mysterious neighbor Joe. On the night of the killing, as they confront the many meanings of their crime and finally relax and laugh and love again…there's a knock on their door."

The design team for Massacre includes Andromache Chalfant (scenic design), Cait O'Connor (costume design), Austin Smith (lighting design), Daniel Baker (sound design) and Andrew Diaz (properties).
