Carla (Chyler Leigh) is cornered at an old friend's funeral by a detective (Mathew St. Patrick) interested in her clique's 1986 high-school graduation and the events that may have led to the deceased's murder.

In 1987, Sam and Carla get surprises upon their return from London; Aaron has "mix-ups" with Jenna; and Will gets advice from a former cellmate.

To make a case for retrieving her baby in 1988, Sam needs help from Will, who breaks the law to do so without knowing her end goal; Jenna's mother helps celebrate her first movie role; and Craig declares to Will his intentions regarding Sam.
