The 39 Steps is a melodrama adapted from the 1915 novel by John Buchan and the 1935 film by Alfred Hitchcock. Patrick Barlow wrote the adaptation, based on the original concept by Simon Corble and Nobby Dimon of a two-actor version of the play. Barlow had originally intended to portray the character of Richard Hannay, but focused solely on rewriting the original version.[1]
The play's concept calls for the entirety of the 1935 adventure film The 39 Steps to be performed with a cast of only four. One actor plays the hero, Richard Hannay, an actress (or sometimes actor) plays the three women with whom he has romantic entanglements, and two other actors play every other character in the show: heroes, villains, men, women, children and even the occasional inanimate object. This often requires lightning fast quick-changes and occasionally for them to play multiple characters at once. Thus the film's serious spy story is played mainly for laughs, and the script is full of allusions to (and puns on the titles of) other Alfred Hitchcock films, including Rear Window, Psycho, Vertigo and North by Northwest.

三皇五帝，夏商两周。一千年的征战与诸侯的纷乱，在苍茫大地上只残存焦土和沙砾。
公元前215年，荆轲刺秦后12年，嬴政平六国之乱，还天下以宁静。击匈奴、征百越；筑万里长城，修南北灵渠；四海版图，一统寰中。
满目疮痍的家园重焕生机，千疮百孔的人心却在伤痕累累的沉重过往里倍受煎熬。
盖聂，天下第一剑客。
他，曾是秦王第一侍卫，为保故人荆轲之子，孤身一人与秦为敌，携荆天明喋血出逃。三百敌兵列阵，忠义两相发难，他以道抉择；
他，背负骂名，危难之际，以德报怨，换取墨家机关城最终安宁；
他，重伤昏迷，幸得镜湖医仙端木蓉相救，互生情愫；生死关头，芳华刹那。
秦王、荆轲、天明、高渐离、卫庄……历史多少豪杰，却总难逃风沙掩盖；兼爱、非攻、易水、寒波、渊虹、残剑，生死、离合……酣畅淋漓的爱恨情仇分外刻骨铭心。
风萧水寒，此地一别，转身，便是千年流转，物是人非。
