Air-crash genius Miranda Chase, a high-functioning autistic investigator, races to an impossible scene: a small jet crashed on a rapidly calving Alaskan glacier. She must solve the crash before the jet disappears into the ocean.

Facing a ticking clock, Miranda relies on her brilliant, unconventional mind, her dedicated team, and an unexpected "gadget" to survive salvaging the critical evidence.

As she navigates the perilous ice and a race against time, Miranda and her therapy dog discover that sometimes the most ordinary tools can hold extraordinary power.
