In the late '70s when sex talk is still taboo, the life of a straitlaced skin doctor and specialist in venereal diseases is turned upside down when he starts moonlighting as a sex columnist under the pseudonym "Doctor Climax".

Doctor Nat, a dermato-venereologist who once dreamt of writing adventure novels and becoming a published author, ends up as the columnist behind "The Climax Question" a space for answering questions everyone wants to ask but dare not. From masturbation and premature ejaculation to foreplay, STDs, and more, the column discusses forbidden subjects while keeping the inquirers' identities anonymous. Through his work on the newspaper column, Doctor Nat grows closer to Linda, the publisher's art department head. Their budding connection threatens to jeopardize not only the doctor's marriage with his perfect wife, Tukta, but also his family's old-money status.
