"Something's gone very wrong behind the idyllic façade of Jan and Adam's Brooklyn brownstone," read press notes for the two-character piece. "At 9:10 PM, they're reveling in the freedom of having waved off their young son, Greg, to a neighborhood sleepover. By 9:15 PM, they're both in tears. By 9:25 PM, things are way past tears."

The design team for Fifty Words features Neil Patel (scenic), Michelle Habeck (lighting) and Mimi O'Donnell (costume) with sound by Fitz Patton and Josh Schmidt (who also provides musical composition).
