in the world that luke hemmings grew up in, you could only hang out and fall in love with people who had the same hair color as you. the people you could talk to would be in color, everyone else was in black and white. if you talked to anyone who you saw in black and white, you would be arrested because then you were messing with the "natural way of life". the government knew exactly who you could and could not talk to. your soulmate was only suppose to have the same hair color as you, and this was how the government kept everything in check. another rule they had was you could not be gay and if you were this was punishable by death. but what happens when four guys with different hair colors all accidently bump into eachother in the hallway, and they all see each other in screaming colors?
