Suen:  Tina 's safe .
Cleopatra: What 's that ?
Suen: There 's a location device in her underwear . We can detect her from as far away as 500 meters .
Cleopatra: When did you plant it ?
Suen: You wear _ one _ , too . So do I. It 's made from special fabric and a thin semiconductor which works by body temperature and friction .
Cleopatra: Wow ! Cutting - edge technology .
Nacky: You mean , I got one too ?
Suen: Not yet , but I can rig one up for you if you like .
Nacky: No thanks . I like my freedom .
