Fleabag arrives with a bang and spins through London, grasping at anyone and anything that might keep her head above water.

Haunted by memories of her dead best friend, dumped by her emotionally fragile boyfriend and now desperately trying to sell her stolen goods, Fleabag attempts to rekindle romantic fires to distract her from the mayhem of her life.

Fleabag helps her inappropriate brother-in-law buy a present for Claire, who is organising her own surprise birthday party. Also, Fleabag reconnects with a toothy friend while on the hunt for a date.

Fleabag and her sister, Claire, reluctantly visit a female-only silent retreat. Their enforced silence is interrupted by an unusual neighbouring workshop, explosive secrets coming to light, and a surprising connection with an old acquaintance.

On the anniversary of her mother's death, Fleabag and Claire return to their family home for the annual memorial lunch. Things get heated between Fleabag and her godmother, who muscles her way into the occasion and reveals some strange plans.

Fleabag takes a date to her godmother's "Sex-hibition", only to discover that there are a few shocks are in store for her: a declaration of love, a familiar piece of work, and an entire wall of surprises.
