One runs the business. The other is married to a wealthy businessman and has a daughter named Clare. Jack learns that Hamish Logan, once co-founder of the empire, had an Aboriginal wife. Jack is their son and therefore part of the Logan family. He falls in love with Clare and she becomes pregnant. Her parents shield her from Jack and want her to give up the child. Jack now faces the task of claiming his inheritance and getting his wife back with the child he has never seen.
