A man (Alan Rosenberg) whom Catherine flirted with at a bar reappears in her life as a suspect in a murder investigation of a woman who was shot and killed.

Rush reopens a case involving an elderly woman who died of natural causes but had been using the identity of another woman who disappeared in 1954. The team searches for clues to find out what happened to the woman whose identity was stolen.

With Keith out of town on business, David gets taken for a ride by a hitchhiker. Meanwhile, Nate feels out of place in a bereavement group, Ruth tries to play matchmaker--to George's chagrin, Claire feels empty after a critique of her self-portraits, Brenda and her mom go back to school, and Federico gets an unexpected visitor at work.

Ruth goes on a fossil hunt with George, and digs up Sarah and Bettina. Claire focuses her talents on Edie; Federico tries to unload on Sophia; Vanessa does some part-time detective work; Keith goes 'out' to a bar with his co-workers; David drowns his stress; Nate dares Brenda to be honest with Joe, and receives some relationship advice himself.

Ruth is giddy about going to a tantric workshop with George, who retreats to the family's emergency shelter. Meanwhile, David's last bite at a sushi restaurant threatens to cost him--and Keith--a lot more than the bill; Nate drops a bomb on Barb, which sparks a counterattack; Claire fights Russell over credit for her latest photos; Margaret's hospital stay helps Brenda and Billy begin to heal their rift; and Vanessa shows she can beat Federico at his own game.
