A year after Emma Henson, a young, genius biotech scientist, dies in a covert AI brain-chip experiment, her father, Josh, has nothing left to live for and vows to get revenge on the Silicon Valley CEO responsible. Josh has thirty days to make his homemade bombs and to say goodbye to life. To give himself courage in the countdown, he records daily video messages to his lost "Em." Memories flood him as he searches for the moments in Emma's short life where he could have been a better father and saved her. Fueled by the horrific memories of Em's death--her body and brain devoured by the AI "infinity" system--he grapples with constructing and testing his DIY bombs as his thirty days start to run out, and Emma's voice returns to him, speaking with him as he sets to complete his mission. He worries that he's gone insane--he doubts if he can see the violent act through--but Emma's voice insists he continue on his path toward murder and mayhem. Josh tries to resist his daughter's voice as it attempts to take full control of his body. But is it even her? Or is it a ghost, a psychotic delusion, or the AI system that is controlling him?
