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.

The six friends gather for a wedding; Brewster suspects Will of subterfuge; problems arise with Carla's job and one promised to her by Jenna; and an old truth throws Detective Marjorino for a loop.
