Based on the Japanese terror manga by Shun Umezawa, Equals tells the story of Alex and Ruth, two twentysomethings who meet through a dating app, and have an amazing first date with a real connection. Within no time they are inseparable, a happy couple. They move in together and share hobbies and tastes, the same breakfast mug and even the same toothbrush. Gradually Alex starts to notice that Ruth is changing, until she no longer looks like herself, but like a mirror image of him.
