Mila can't remember anything before the fire that took her father's life. It's normal to have some memory loss after traumatic events, but Mila doesn't remember if she's ever learned to ride a bike, or if she's ever been in love. Nothing.
What she doesn't know is that she isn't supposed to remember—that she was built in a computer science lab and programmed to forget. Because if she remembers, she might discover her true identity.
The question is: If she relived the fire, what would she see?
