S1·E193 The Amnesia Patient - Part 1

CID officers come across a car accident while out driving. They rush to help the driver, who, seconds before passing out, says she has killed someone. But upon awakening, she can no longer remember anything- no details about who she may have killed, not even her name. Who is this woman? Who has she killed? Can CID solve this mystery with help from this amnesiac, perhaps at her expense?
