Tate knows how to make weapons out of oranges and lighter fluid. The Archer family also uses passwords like the chemical formula for strychnine. To say that Tate Archer is a little bit above average intelligence as compared to other teenagers is an understatement. His father's been training him and preparing him his whole life under a strict regimen and Tate's been resenting all the work he's put himself into. That is, until he gets ahold of the scanner.
What if aliens did exist and there was a way to prove it? What if all you had to do was take a scanner and scan someone for a blue or red light? Would you believe in aliens then?
Welcome to Tate and Christina's world. Tate unlocks a scanner from his dad's laboratory and when he brings it to school, their world is just about to get a little smaller. Blue means human and red means H2. When Tate scans himself and his girlfriend, he is blue and Christina is red. Immediately the scanner draws attention, some from the wrong crowd and when Tate's father shows up, he is shot at the outset of a high speed chase. Tate is forced to send a text to his estranged mother from his dead father's phone. Tate, his mother and Christina are all on the run and human or not, no one is safe.
Walter Jury's and Sarah Fine's Scan is reminiscent of Stephenie Meyer's "The Host." Both are about aliens that look just like humans invading Earth. "Scan" is a lot more action-packed, though. If you love visualizing action scenes as though they were projected onto the big screen, you'll love "Scan." It's not just about three people on the run, but ultimately it's about the length of trouble someone will go through to protect the one they love. At first Tate is angry when he finds out that his girlfriend, who he never thought he'd have a chance with, is H2 and is afraid she'd betray him. But when she proves her loyalty, he realizes it doesn't matter what she is. All that matters is that when everyone else views her as the enemy and is literally trying to grab a piece of her, he's got to hold them back in any way he knows how.
And when the scanner goes missing in the end, you know a world war of epic proportions is about to begin.
