Criminal investigation
Porcelain: Forensic Medicine
Russia and the United States: Field Service
France and England: Non-staff consultants (still capitalists)
American porcelain, British, French, Russian and Soviet (brother bones)
Plot line 60%, emotional line 40%
Including disputes (American porcelain), suspicion (English and French), all villains, bad people sincere, forced love (Russia and the Soviet Union)

Purpose: abide by laws and regulations
