As devout Jehovahs Witnesses, sisters Alex and Luisa and their mother, Ivanna, are united in The Truth. Alex looks up to her confident older sister, while striving to follow in Ivannas footsteps as a good Witness. But when Luisa starts to question the advice of the Elders, she makes a life-altering transgression that threatens to expel her from the congregation. Unless Ivanna and Alex can persuade her to return, they must shun her pletely. This challenge bees more painful when their family is faced with another heartbreaking test of faith. Written and directed by Daniel Kokotajlo, a former Jehovahs Witness, Apostasy provides rare insight into the plex nature of faith, family, duty and love.不要单独行走规定了一家人不可独自外出，即使在危险来临之际也能相互照应；为躲避危险一家人远居乡下，在其住所外大片的玉米地也是一家人远离的禁地，进入其中会制造声音，更可能触发潜藏其中的危机；注意脚下则是要求每一次行走都要非常小心，看清脚下的路，不慎跌倒或者碰撞到其他物品发出的声响，都有招来怪物的可能；不要偏离道路，是对人们外出行走的要求，铺满细沙的道路能够降低人们行走的声音；而一家人设置用于照明与沟通的灯光，在危险来临之际会变为红色，所以红色表示快跑，除此之外，保持绝对安静、任何时候都不要尖叫也要严格遵守。
