I can tell you how hard it is to finish some closing pieces of a longer work of fiction. Some of the beginning, middle and various parts flowed like butter, but sometimes wrapping all those strands into a tidy finish is the hardest part.
Here is the synopsis, which I'll probably modify a bit:
While en route to an appointment, Sarah Easton, student at U.C. Berkeley, is kidnapped through a sublte deception and brought to a remote cabin, where she is forced to record a ransom demand aimed at her father, a hotel magnate. Over the several days of her confinement, she attempts to turn the tables by using her wits and manipulating the strange interpersonal relationships between her three captors. However, as these relationships break down and the day of the exchange looms, her careful planning is thwarted at the last minute and she learns that death is in the works for her. Using every resource to escape, she comes face to face with the unexpected mastermind behind the kidnapping.
I like this picture and think it captures the mood of the setting fairly well:
