A group of three retirement home friends are determined to prove that there is still much for them to accomplish in life despite their age.

Margaret tries to convince Sid to come out to his visiting son; Hank stubbornly refuses to admit he needs glasses; Charlie tries to help him cheat on an eye test.

Margaret scores an invite to an exclusive foodie potluck for Thanksgiving and takes Sid as her plus one, leaving Hank and Charlie to find a backup plan.

Margaret begins dating Karl, a fellow Shady Meadows resident who may or may not be the Zodiac Killer. Meanwhile, the guys are hunting for a different kind of criminal: a serial non-flusher.

Hank signs up to host a Shady Meadows closed-circuit TV show but is quickly replaced by Sid, who dishes out hot retirement home gossip on-air; Margaret helps Charlie woo a widow at her bereavement support group.

Hank, Charlie and Sid prepare their Friend-iversary party, and don't include Margaret. Noticing the tension between Hank and Sid, Margaret encourages Sid to speak up for himself. Meanwhile, Sid has his sights set on the patio for their party and attempts to convince the cat ladies to release it to them.
