Head Trip: One Case of Super Twins

When two brothers are conceived a month apart--called superfetation--and are born as twins eight months later, one of them is a full-term baby and one is an "intruder" preemie. This anomaly affects them their whole lives as one twin struggles to achieve and the other struggles to subvert. They are envious of one another and spend a lifetime finding out who each are. Their journey turns in to a real head trip, both literally and figuratively. The envy in one twin grows into a real hatred for the other.
