It is 1980 and Jan Stenbeck wants to take the family business in a new direction. He tries to realize his vision of mobile telephony in Sweden and ends up on a collision course with his sisters, especially the older Margaretha who protects the company's traditional industries of forestry and steel. He challenges the Televerket monopoly and at the same time has plans to close the family business's steel mill in Fagersta. The enemies are increasing.
