Ruth & Alex is set over a weekend where a couple (Morgan Freeman and Diane Keaton) must decide whether or not to sell their Brooklyn walk up of 40 years. The story takes a comedic turn when the dynamic couple have to contend with eccentric open house guests, their pushy realtor niece, and the health of their beloved family dog — all while navigating a New York on edge from what turns out to be an media-generated terror threat.
