Nadine Walsh is determined to make her summer garden party the event of the year.

Everyone deserves a celebration after the year they've had. A chance to forget.

As she prepares to welcome her guests, however, Nadine can't help but be distracted. Her husband is of little help to her. Her two grown children are consumed with their own concerns.

But it's Nadine's own secrets that threaten to destroy her perfect party.

By the end of the night, Nadine will be standing over a dead body in the basement.

But which of her guests will she have murdered? And why?
