In the new season, Trace (Metcalfe) returns from tour, determined to get back to the life he had in Chesapeake Shores with Abby (Ory), but finds it might not be possible to go back to the way things were. As he settles back in at The Bridge, a talented, but stage-shy waitress-songwriter (Lanie McAuley) catches his attention.

Abby faces an ethical dilemma involving an important new client. When doing the right thing puts her job on the line, she reevaluates her work-life balance and meets an intriguing new man (Greyston Holt). Mick (Williams) faces his own professional peril, when it’s revealed that a once trusted vendor has been cutting corners and he implicates Mick. As he and Megan (Niven) explore their connection, while trying to avoid the mistakes of the past, his legal distractions threaten to pull him back into old habits.

Changes are in store for all of the O’Briens as Kevin (Penny) and Sarah (Jessica Sipos) make plans for their future; Jess (Mailey) and David (Carlo Marks) consider going back to where it all started; Bree (Ullerup) enlists a talented producer to stage a loosely autobiographical play that gives her new insights into her relationship with Simon (Oliver Rice); and Connor (Francis) considers a career opportunity and ponders his feelings for Danielle (Britt Irvin). Not a moment too soon, Nell (Ladd) returns to Chesapeake Shores with some much-needed sage advice.
