'The Power', a show about women, is set in a world where they have become more powerful than men and have taken over the majority of the government. It is told from the viewpoint of different characters, and it reveals similarities and differences between the worlds controlled by men and women.
Allie has a voice inside her head, which helps her escape from her foster parents and find a place where she belongs. SPOILERS AHEAD
What is Allie's Voice?
The origins of the power in the Prime Video series are still unknown, raising many questions about its true potential. This power is only developed in young girls, and its only function is to generate electricity.
The narrative of Allie's situation will evolve further in the future. It's all about the consequences of the newfound power in women's hands and how it affects the world. It's also about the fact that she's led down a path that initially seemed right, but became more treacherous as the day progresses.
The Voice may be Allie's conscience or a part of her personality that has kicked into survival mode and wants her to fight. It recognizes the change in her body and guides her to utilize the power at the appropriate time and escapes.
Allie talks herself through tough times, even though every other woman does the same thing. This could be her self, keeping her spirits up in the worst times and empowering her to excel.
The other possibility is that the Voice is the power. As previously stated, the true origins and nature of the power are not yet known, so it is possible that the Voice has manifested as the Voice in Allie. Some other character may also begin talking to other girls and possibly develop some sort of connection, possibly telepathy, between them.
