A group led by a 'boss' arrives in Granton to settle a score with the Clare family after learning Ms. Clare, the eldest daughter, has returned and will attend the patriarch's 60th birthday. At the party guests toast Mr. Clare while relatives tease about Emma and local billionaire Ian, who didn't come. The evening pivots when a woman appears and says, "I'm your long lost daughter, Alice." Jason erupts with accusations about a love child. The revelation shatters the celebration, forces the family to demand proof, and leaves the planned confrontation unresolved.
