Something's gone very wrong behind the idyllic façade of Jan and Adam's Brooklyn brownstone. At 9:10 p.m., they're reveling in the freedom of having waved off their young son, Greg, to a neighborhood sleepover. By 9:15 p.m., they're both in tears. By 9:25 p.m., things are way past tears. Alternately funny and frightening, Fifty Words is an expansive look at modern marriage, as seen through the looking glass of one couple's long night's journey into day.
