Flack is a sharp, cynical dramedy that follows Robyn, an American public relations executive living in London. Working for a high-powered PR firm, Robyn is a master at cleaning up the messes of wealthy, famous, and often morally bankrupt clients. She is brilliant at her job, navigating scandals with cold efficiency, but her professional success stands in stark contrast to her chaotic personal life, which is plagued by addiction and deep-seated emotional trauma. The series explores the dark underbelly of celebrity culture and the lengths to which people will go to protect their reputations. As Robyn juggles the demands of her demanding boss, Caroline, and her colleagues, she finds herself increasingly entangled in the very scandals she is paid to bury. The show balances biting humor with intense drama, examining the cost of living a life built on lies and the difficulty of maintaining one's humanity in an industry defined by artifice.
