Ivan is a tightly wound philosophy professor. His wife, Prue, is quite the opposite: a pioneer in the emerging field of biolinguistics, she is bold and vibrant, full of life and feeling. Thus far, they have managed to weather their differences. But lately, an odd distance has settled in between them. Might it have something to do with the arrival of the college's dashing but insufferable new writer-in-residence, whose novel Prue always seems to be reading? Into this delicate moment barrels Ivan's unstable father-in-law, Frank, in town to hear Prue deliver a lecture on birdsong that is set to cement her tenure application. But the talk doesn't go as planned, unleashing a series of crises that force Ivan to finally confront the problems in his marriage.
