A train’s whistle sounds in the dead of night as snow falls on deserted tracks. In the city, a woman prepares to leave on a journey that will change her life. In the country, a man drives to his final destination.

A young woman prepares to depart on a journey that will take her into the very heart of darkness. Before she can leave her apartment, she has a few loose ends to tie up.

Alex Davenport wakes up on the train and finds that her travelling companion, Harold Lang, is nowhere to be found. Don, the conductor, is not forthcoming about what is happening. Alex is left to wonder why her friends are there, who the ballerina is, and whether this is a nightmare or a pipe dream.
