Aliens invaded our planet many years ago.
Settling into our bodies and canceling our will, they walk among us looking like human beings.
Their domination provides for a general welfare for all, as long as you don’t want to be independent like some rebels.

But the procedure does not go the right way and their consciences coexist in the same body.
A problem when they fall in love with two different guys.
