Kill Switch (also known as Redivider) is a 2017 American-Dutch science fiction film, directed by Tim Smit in his directorial debut, from a screenplay by Charlie Kindinger and Omid Nooshin.

It stars Dan Stevens as Will Porter, a former NASA pilot-turned-physicist recruited to reverse the damages of harnessing unlimited quantum energy, at the cost of either one of two universes colliding.

Sometime in the near future, physicist and former NASA pilot Will Porter is recruited by Alterplex, a power company that has built a massive tower that taps into unlimited quantum energy.

Porter has been sent to The Echo with a cube device called the "Redivider" believing it will balance the power transfer between the two universes and set things right.

Instead, he learns the device is a kill switch that will destroy The Echo forcing him to decide which universe to sacrifice in order to save the other.
