"Flack" is a drama about a take-no-prisoner public-relations professional named Robyn who is an American working for a London based firm. Robyn is unflappable in her PR job and her ability to get her high-profile very wayward ill-behaved celebrity clients out of potentially embarrassing situations is unparalleled. However, her ability to get her clients out of these messes does not translate into her own life as Robyn tries to get her own life back on track while juggling her job.
