During a medical crisis at the Zimmer mansion, the elderly Mrs. Zimmer suffers a severe seizure. A doctor diagnoses it as a simple seizure and prepares to administer a sedative, but a maid intervenes, insisting the symptoms point to acute poisoning from a sleeping pill overdose. The doctor and other staff dismiss her, citing the woman's perfect health and the maid's low status. To stop the dangerous treatment, the maid stakes her career on her first-aid training and personal experience with such overdoses, pleading for a one-minute search of the room for an empty pill bottle before it is too late.
