2014年5月5日，不死小强又要回来了！福克斯酝酿数年的《24小时》电影版最终变成这样一部迷你剧，作为剧迷来说未尝不是件好事，因为12个小时迷你剧远比两个小时的电影过瘾多了；而且，如果迷你剧获得成功，还有可能使得系列重启，将来会有第十季。继包小强逃离纽约之后，飘扬过海来到了英国，迷你剧将在伦敦展开。昔日的国防部长James Heller已经登上美总统宝座，此次出访英国，受到恐怖分子威胁，而销声匿迹多时的Jack Bauer感受到使命召唤，也将再度出马。不过CTU的分店还没有开到英国，就目前消息来看，此次的与恐怖分子对抗的机构应该是CIA中央情报局。Four years after the events of Day 8, Jack Bauer remains a federal fugitive. Meanwhile, amid growing concerns over the use of US military drones in combat, President James Heller pays a visit to London to negotiate a treaty to continue their basing on British soil. Having heard rumors of an imminent attack against Heller, Bauer resurfaces in the city, where he is apprehended by the CIA and forcibly recruited into joining their investigation. As forces within the White House conspire against him, Bauer realizes that the complexity of the plot extends beyond a presidential assassination, and that the consequences of a successful attack will alter the course of history. With the help of a disgraced CIA agent and a hacker collective preaching free information, he must confront an unseen enemy whose personal vendetta threatens to push the world to the brink of war.
