Ghost

Sophie is dead, but she's somehow still here: watching but unable to interfere as her family grieve.

Ghost follows Sophie, who has recently died in a tragic accident. However, instead of passing over to a better (or worse) place, she is stuck watching her family and friends as they grieve.

They cannot see or hear her, so she cannot intervene, and she can only watch as her relationships are unraveled and each person in her life struggles with how to process sudden tragedy.
