For years Yellowbeard had looted the Spanish Main, making men eat their lips and swallow their hearts. Caught and convicted for tax evasion, he's sentenced to 20 years in St. Victim's Prison for the Extremely Naughty. In a scheme to confiscate his fabulous treasure, the Royal Navy allows him to escape and follows him, where saucy tarts, lisping demigods and some awful puns and punishments await.

英国无厘头鼻祖“巨蟒小组”（Monty Python）曾以《巨蟒与圣杯》、《万世魔星》等片风靡全球，直到1989年主力之一格雷厄姆·查普曼因病逝世，特瑞·吉列姆、特瑞·琼斯等人各自单飞，小组才逐渐走向解体。今日，格雷厄姆·查普曼传记动画片《撒谎精自传》首度曝光预告，巨蟒老友团重聚为本片配音，恶搞无厘头风格比以往有过之而无不及。
