The movers and shakers in Singapore get involved in behind-the-scenes political and business activities, romantic entanglements, and murder. Nicol Williamson plays the wealthiest man in Southeast Asia. Barbara Hershey is his married antagonistic daughter who starts an affair with an ambitious American banker (Bruce Boxleitner) and who also seems to have the attention of her father.
