Isteal It Com Better -

Let me outline the plot. Protagonist could be a tech whiz who steals a cutting-edge tech device from a corrupt CEO. The device, let's say, is an AI that controls smart homes but has a sinister backdoor. The protagonist wants to reprogram it to protect user privacy. Then the CEO hunts them down to get the AI back, but the protagonist must present the improved version to the public to change the technology landscape.
