故事设定在第二季事件的152年后。

　　It’s official: Resident Alien has been renewed for a fourth season at a new NBCUniversal home, USA Network, moving from cable sibling Syfy.
　　As Deadline reported exclusively last month, the quirky sci-fi comedy-drama was not likely to continue on Syfy, with a move to USA as its most viable option to get a fourth season with a significant budget reduction.

　　在最后一季中，June不屈不挠的精神和决心使她重新加入了打倒基列国的战斗中。Luke和Moira加入了反抗军。Serena试图改造基列国，Lawrence大主教和Lydia嬷嬷则在面对自己造成的后果，而Nick面临着严峻的人格考验。June旅程的最后一章强调了希望、勇气、团结和韧性在追求正义和自由过程中的重要性。
