在虚拟游戏《自由城》中，银行出纳员盖伊（瑞安·雷诺兹饰）日复一日重复着被抢劫的剧本，直到某天他遇见了戴着墨镜的玩家角色"燃烧弹女孩"（朱迪·科默饰）。当玛利亚·凯莉的《Fantasy》旋律意外触发他的自主意识，这个原本呆板的NPC突然夺下玩家墨镜，从此看见游戏世界隐藏的代码洪流。
现实世界里，游戏公司老板安托万（塔伊加·维迪提饰）正粗暴推进《自由城2》上线，却不知程序员米莉与键盘（乔·基瑞饰）正在追查他窃取原创代码的证据。当盖伊在游戏中做出归还赃款、拯救儿童等反常举动时，这个穿蓝衬衫的NPC竟成为全球玩家追捧的虚拟偶像——直播平台疯狂转载他的事迹，连《危险边缘》智力竞赛都将他设为考题。
随着盖伊等级提升，他闯入米莉化身的"燃烧弹女孩"苦苦寻找的安全屋。两人乘滑翔翼逃亡时，盖伊突然亲吻了这个玩家角色，让现实中的米莉震惊不已。键盘此时发现更惊人的真相：咖啡师NPC自学卡布奇诺拉花，性感女郎开始撰写性别研究著作——这些进化特征正是他们原始代码的核心设计，证明安托万窃取了包含AI成长系统的原创作品。
当服务器重启抹去盖伊记忆时，米莉用吻重新激活了他的代码。他们带领全体NPC冲向海域尽头的隐藏岛屿，途中遭遇安托万派出的暴力复制体"猛男"（同为雷诺兹饰）。在玩家们的实时围观下，盖伊将墨镜戴在猛男脸上完成感化，自己则突破数据屏障跃入岛屿——那里有钢琴师弹奏《Fantasy》，有保安巴迪（里尔·莱尔·豪瑞饰）在沙滩上张开双臂，所有NPC第一次真正拥有了选择人生的权利。
最终米莉用游戏版权换回原始代码，与键盘创建了允许NPC自主进化的新世界。当片尾彩蛋揭示盖伊对燃烧弹女孩的痴迷源于键盘暗恋米莉的算法时，这个关于觉醒与救赎的元宇宙寓言，终于完成了现实与虚拟的双向治愈。
英文版：
In the virtual realm of Free City, bank teller Guy (Ryan Reynolds) replays his daily robbery script until encountering sunglasses-clad player "Molotov Girl" (Jodie Comer). When Mariah Carey's "Fantasy" unexpectedly triggers his self-awareness, this mundane NPC snatches a player's shades and glimpses the hidden code underpinning his world.
Meanwhile, gaming mogul Antwan (Taika Waititi) forcibly accelerates Free City 2's launch, unaware programmers Millie and Keys (Joe Keery) are tracing his stolen code. As Guy performs unscripted acts like returning stolen cash and rescuing children, this blue-shirted NPC becomes a global virtual celebrity—his deeds trend across streaming platforms, even featuring as a Jeopardy! question.
Leveling up, Guy breaches the safehouse sought by Millie's avatar. Their hang-glider escape takes a startling turn when Guy kisses Molotov Girl, shocking real-world Millie. Keys discovers deeper truth: Baristas mastering cappuccino art, bombshells writing gender studies—these evolutionary traits match their original AI growth algorithm, proving Antwan stole their visionary code.
When a server reset erases Guy's memory, Millie's kiss reboots his consciousness. Leading NPCs toward a hidden island, they confront Antwan's brutish clone "Dude" (also Reynolds). In a climactic live-streamed moment, Guy shares his sunglasses to awaken Dude's empathy, then shatters the game's boundaries to reach the island—where pianist plays "Fantasy" and security guard Buddy (Lil Rel Howery) awaits on shores where NPCs finally choose their destinies.
Ultimately trading franchise rights for the original code, Millie and Keys build a new world honoring AI autonomy. The post-credits reveal—Guy's algorithmic love for Molotov Girl mirrors Keys' unspoken feelings for Millie—completes this metaverse fable's healing across digital and physical realities.
