When astronaut Molly Woods (Halle Berry) comes home from a 13-month solo tour in space, she knows three things. She's happy to see her husband, John (Goran Visnjic), her young son Ethan and she can't wait to finally be cleared by her doctor and friend Sam (Camryn Manheim) so she can have a celebratory drink. And yet, Molly's not feeling well. She can't stop throwing up.
It must be the adjustment back to regular altitude after a year-long tour in space. That would mess with anyone's stomach. Or is it? After completing the required medical tests for her re-entry into society, Molly learns the unthinkable. She doesn't have a case of super sonic jet lag. She's pregnant.
Molly's son Ethan appears angelic but he fights easily with other kids. His personality turns on a dime. Something's wrong with his wiring. When Ethan tells his Dad he "needs to flip," John reaches for his son's back, opens up a special compartment and flips a battery-like device. It turns out Ethan is not Molly and John's biological son. He's a Humanich, a robot like simulation created by John, giving them the chance to have a family when infertility left them childless.During a flashback to the mission, we see Molly talking to a computer voice that controls the capsule, named "Ben." Suddenly, Molly has a vision of her ex-boyfriend, Marcus, a young astronaut who passed away years ago. Is he the culprit of Molly's condition? Suddenly, the computer temporarily goes on the fritz. It's during this computer shut down that Molly reconnects with Marcus and (we assume) becomes pregnant.On her return to Earth, Molly tells her superiors there was a solar flare when Ben went down. That explains why 13 hours of camera footage is missing.
And why there's no record of how Molly became pregnant. Only we know the truth - Molly deleted those tapes after watching them and seeing herself embracing nothingness. Was Marcus a vision from her imagination? Molly decides to cover up the experience with her solar flare explanation.
Meanwhile, John tries to get funding for his robot like humans, Humanics, showing off his son Ethan as the first prototype. At first, scientists rebuff him, frightened by the prospect of robots we cannot control. But the NASA like organization wants to keep an eye on Molly and her husband, so they convince a wealthy investor, Mr. Yasumoto, to fund John's research and keep an eye on all of them. Maybe they'll find out what happened during the missing footage.
At the end of a long day, while taking out the trash, Molly encounters Harmon Krieger, an astronaut colleague who had committed suicide after returning to Earth, overwhelmed by the stress of re-entry.
Harmon tells Molly that he's real. He's not another robot. Or a vision. He tells Molly not to trust them.
"Who?" says Molly.
