Can Sally get enough time on her own to report to her headquarters and foil the criminals?    

To discover who committed two murders on his watch, Detective Inspector Bob Crane instructs Detective Sergeant Sally Jones to go undercover into the seedy club of the suspect, criminal gang boss Jack Stewart. Changing her appearance and dying her hair blond, she hopes to attract the attention of Stewart. He likes Sally’s new look and, although suspicious of her motives, sets her up to be his companion in return for her sexual favours.
Stewart’s henchman, karate expert Lau Chang, on instructions from Stewart, constantly watches her. He has mesmerising eyes that Sally finds difficult to cope with or resist. Sally discovers that Stewart and his gang are planning a bank raid involving the use of weapons. Sally is desperate to contact her headquarters to pass on details of the raid, but the ever-watchful Chang and the suspicious Stewart thwart her at every turn.
