Escape to Chesapeake Shores this summer when Season 4 of the Hallmark Channel drama premieres Sunday night.

The last time Chessies saw the characters, in the Season 3 finale, there was both heartbreak — Trace (Jesse Metcalfe) and Abby (Meghan Ory) breaking up — and joy — Sarah (Jessica Sipos) moving back to be with Kevin (Brendan Penny).

But what will these new episodes bring for the O’Briens and their loved ones?

“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,” the Season 4 synopsis shares. “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 (Treat 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.”

While that’s what’s to come throughout all of “Chesapeake Shores” Season 4, keep reading to find out what’s about to happen in episode 1, which was directed by Terry Ingram and written by Michael Berns.
