Sam and Erica's mother and father host a lunch for Lenin's parents to celebrate the baby news, but Barb doesn't seem to be taking it well and makes the event uncomfortable for everyone. In an effort to find out what's behind Barb's reaction, Doctor Tom sends Erica back to 1969, when her mother was a 17-year-old high school student.

Dr Naadiah realises that Doctor Tom is repeating his old patterns of behavior outside the office and she encourages him to return his ex-fiancée Amanda's calls.
