In the coastal town of Alden, Maine, Hope and Jack Kelly have settled down to a life of wedded bliss.

When Jack’s old rival, Ryland Finn, threatens his fishing territory, he ignites emotions that propel the Kelly family toward circumstances that will either tear them apart --- or be the path to their family’s future.
