Katrina Kim may the black sheep of her family and slightly unhinged, but she isn’t a stalker. Her obsession with her co-worker, Kurt, is just one of many coping mechanisms. But when Katrina finds a cryptic message from Kurt that implies he’s aware of her surveillance, her tenuous hold on a normal life crumbles. Driven by compulsion, she enacts the most powerful ritual she has to reclaim control --- a midnight visit to the Cayatoga Bridge --- and arrives just in time to witness Kurt’s suicide. Before he jumps, he slams her with a devastating accusation: his death is all her fault. Horrified, Katrina combs through the clues she’s collected about Kurt over the last three years, but each revelation uncovers a menacing truth: for every moment she was watching him, he was watching her.
