Death Role

This could have been the start she was looking for. It could have been, but it was fast turning into a nightmare rather than a dream come true.
Every actor and actress is given a role to play. Her script character was supposed to be fictitious. Her script character was supposed to get a threat note painted on her mirror, get hit by a car... and die. Not her.
The filming crew is huge, but who could possibly want her dead? Time runs short as she realizes she only has a few scenes left. She is still assigned the death role, only... with her own life.
