When two parents decide to predetermine their child's genetic makeup the result is a split in the zygote during the mitotic process. In other words, there now exists two separate children with two entirely different genetic makeups. Separated at birth, the children grow up to look, act, think, and become two completely contrasting people. When one of the children, now a down and out man named Vincent is about to be killed by a loan shark, his 'twin' brother Julius sets out to save the brother he never knew he had. From there the two set out to learn about each other and their long lost mother.
