"Every single person on this planet is born with Heterochromia - which means that you're born with two different eye colours. But not only this, you also have a soulmate born with the same eye colour as you. One of your eyes is your own colour and the other eye is your soulmate's eye colour. When you look in your soulmate's eyes for the first time, you will find out which eye colour is yours as they turn back to their natural form." Everyone around Alex seems to have found their soulmate already while she is still alone waiting for the moment when she will finally meet her significant other. So what happens when her best friend drags her along to a concert and her eyes change colour during the show?
