An old feud comes back to haunt the Lee family. A seed sown decades ago blossoms into a fraternal battle, putting the carefully planned succession at risk. But it’s not the only front on which Samsung is fighting for its survival.

In this brand-new 10-part series from the BBC World Service, we take you behind closed doors - inside the billion-dollar deals and the family power struggles that shape global empires. When your relatives are also your business partners, every decision is personal. In these dynasties, the boardroom isn’t just about profit - it’s about survival.
