Deadly Isolation (2005)

In a quaint and quiet island community off the coast of Maine, Susan is a young widow suffering from deep grief for the loss of her husband, Ron. Two escaped convicts suffer from their own kind of deep grief at the loss of their diamonds stolen in a heist they participated in the year before, spear-headed by Susan’s now late husband. One of the convicts, poses as an old college friend of Ron’s enabling him to get close to a still vulnerable Susan and even closer to the diamonds.
