Police seek a smuggler while doctors desperately comb unprotected New York for a smallpox carrier--unaware that they're actually looking for the same person.

Sheila Bennet returns to New York from Cuba carrying $40,000 worth of smuggled diamonds--and smallpox, which could start a devastating epidemic in the unprotected city. Treasury agent Johnson loses her but keeps doggedly on the trail, while Public Health Doctor Wood searches in vain for the unknown person spreading the deadly disease far and wide. Meanwhile, the increasingly-ill Sheila is concerned only with her faithless husband Matt, who plans to abscond with the diamonds.—Rod Crawford <[email protected]>

Sheila Bennet smuggles some diamonds from Cuba through the port of New York City, but is unaware she is also bringing in a smallpox virus. Doctors cannot diagnose the spreading disease quickly enough, so by the time they discover what they are looking for, Sheila is free--and freely spreading the virus through the city. While both the police department and the city health department are looking for her as a smuggler and virus-carrier, she is looking for her double-crossing husband.—Les Adams <[email protected]>
