A female research scientist conducting experiments on a new anesthetic has a very bad week. Her scheming assistant intentionally scars her face, her almost-fiancee appears to have deserted her and she finds herself being blackmailed by a women she accidentally knocked down with her car.

Nora Goodrich, una experta química que se dedica a la investigación, está decidida a probar en sí misma la anestesia que acaba de inventar. Pero, tras inyectársela, todo empieza a irle mal: su novio la abandona, es víctima de un chantaje y una devastadora explosión le desfigura la cara.
