Spurred on by a Sex And The City-style lunch with her bitchy girlfriends, Edina embarks on a strict regime of water and red meat and enrols herself in a gruelling British Military Fitness programme.

Despite Patsy’s best efforts, Eddy eschews champagne and begins to shed the pounds. But her nights are plagued with visits from God (Marianna Faithfull) and the devil (Anita Pallenberg), who have their own agendas.

Meanwhile, budding playwrite Saffy bumps into a pretentious old school friend, Taylor Johns (Julian Rhind-Tutt), who attempts to use her in his bid to further his acting career, and Patsy decides to see what life is like without her trademark Sixties forelock.

Donkey also stars Helen Lederer as Catriona, Harriet Thorpe as Fleur, Till Blackwood as Lady Candy, Andrea Gillie as Patsy’s PA and Jessica Wilcocks as Minge.
