It isn't the first time that identical twins Gillian and Melina Lloyd have switched identities. Yet it's the first time as adults that they've even considered the childhood prank. Melina, the more impetuous twin, proposes that her circumspect sister take her place as a media escort to NASA astronaut and national hero Colonel Christopher "Chief" Hart.
Although it's an enticing offer, Gillian declines for a very personal reason --- she's preoccupied with whether or not the artificial insemination she underwent that day will be successful. Besides, she warns Melina, such a switch could have unexpected consequences.
