About
"A brutal, twisty meditation on nature versus evil"
Mouse follows a rookie police officer whose path crosses a serial killer investigation built around a controversial theory: that psychopathy can be detected before birth. What starts as a fairly grounded procedural spirals into something far darker and more audacious, packed with brutal violence, moral gray zones, and a mid-run twist that upends everything you thought you knew. It's tense, grim, and unapologetically extreme, carried by committed performances and relentless pacing rather than subtlety. Not comfort viewing, but rarely boring.
Watch it for
the audacious storytelling and a mid-series twist that completely reframes the story.
Maybe skip if
you dislike graphic violence or plotting that leans into melodrama over restraint.
