Sam and Frank Weaver are at their summer home in Harbor Grove, an exclusive resort community on the shores of Grand Traverse Bay in Michigan, for a memorial service for Ruth, Frank's wife and Sam's mother. They are joined by Greg and Janey Anderson and their son Gary, who was a childhood friend of Sam, and Sam’s former lover Pete. They reminisce about their summers spent up at the lake, and as the day progresses into night and the masks come off under the influence of good Scotch, some well-kept secrets and memories that would rather be forgotten are revealed.
