3D Sex and Zen: Extreme Ecstasy is a 2011 Hong Kong 3-D erotic costume drama film released in Hong Kong, South Korea, Australia, and New Zealand on 14 April 2011. It is a new installment of the Sex and Zen series, but more dark and dramatic as well as occasionally paying homage to the humour of the original series.
A conceited Ming Dynasty scholar called Wei Yangsheng believes that since life is short, one should pursue the ultimate sexual pleasure as time permits. By chance, he meets Yuxiang, the daughter of the Taoist priest Tie Fei, falls in love with her on first sight, and marries her. Yuxiang is elegant and courteous under the influence of her father's faith, though her lack of passion cannot fully satisfy Wei Yangsheng's sexual needs. His disappointment is no less than his affection for her. He ventures in search of ways to increase his sex drive and performance in bed.
