Long Time Since (1998)

A beautiful woman has spent a lifetime obsessing about a hit-and-run she caused years ago. She knows she struck something, but left the scene before determining what it was - and if it was alive. She's allowed this event has taken over her life, and now lives in near-isolation with an equally lonely man. When a stranger enters her life that may hold the key to her past, reality becomes stranger than nightmares, and memories cannot be trusted.
