一款名为Nerve的真人大冒险直播游戏正席卷纽约城，游戏参与者有两个不同的选择，要么当“观看者”，要么当“玩家”，观看者付费决定玩家去挑战各种冒险游戏。高中女生Vee（艾玛·罗伯茨EmmaRoberts饰）是个平凡无奇的乖乖女，平日最大的乐趣就是“窥视”学校里的男神JP。她的好友Sydney正沉迷于这个直播游戏里，为了吸引观看者而作出种种大胆行为。受其影响，平日习惯于当旁观者的Vee，也加入了这个直播游戏，成为了“玩家”。她的第一项冒险，就是亲吻一个陌生人。挑战成功后，她才发现这个陌生人Ian（戴夫·弗兰科DaveFranco饰）也是游戏玩家之一。他们俩的大冒险直播，从刚开始的好玩刺激，到逐渐走向失控。他们必须携手逃出这场玩命直播……

本季的重点是「巫术」（witchcraft），Evelyn Poole成为所有主要角色的对手。她知道自己在干什么，她认为自己的行为很高贵。即便她与恶魔为伍，她也坚持认为自己站在天使的阵营中。上一季观众还看到Ethan是个狼人，本季将进一步铺开相关情节，「我们如何对待狼人是本季的重要部分。」此外，Ethan看起来会驱魔，你会看到「他有一段与精神世界打交道的历史」。Malcolm爵士与Vanessa有很深的、如同父亲般的关系，但两人的摩擦会不断升级——因为Malcolm开始和Evelyn打交道，使得团队中的其他人开始疏远他。Victor创造的怪物教给他「什么是爱」，「创造出没有爱的生命，生命一文不值」，但是Victor杀死Brona来给怪物「爱」，这显然不会顺利。

Specialists gather in a top-secret facility to investigate a series of strange deaths on beaches along the Atlantic Ocean. One of the team's scientists (Nana Gouvea) examines video evidence to uncover a possible parasitic explanation for the fatalities. But when a determined detective (Tom Sizemore) sends her the crazed writings of a mysterious homeless man (Jonny Beauchamp), the scientist slowly learns that the actual threat may be more dangerous -- and far older -- than anyone ever imagined. Can she convince her colleagues (led by Eric Roberts) of the true danger before an ancient force rises from the sea to bring madness and death to all of humanity?
