Succession follows the Roy family, owners of media conglomerate Waystar RoyCo. The family patriarch, Logan Roy (Brian Cox), has experienced a decline in health. His four children - removed oldest son Connor (Ruck), power-hungry Kendall (Strong), irreverent Roman (Kieran Culkin), and politically savvy Siobhan (Snook) - all with varying degrees of connection to the company, begin to prepare for a future without their father, and each begins vying for prominence within the company.
