Maverick and Maddi expected junk food, late nights, and video games when school ended—
not getting dragged to work at their parents’ hospital.

St. Magnus Memorial looks normal on the outside…

But inside, it hums like a heartbeat.

Patients vanish.  
Doors move.  
The fog whispers.

When the kids uncover a classified experiment called Project H.E.A.L.—
and a mysterious boxer dog named B.O.O.T.S. trapped deep below the hospital—
they have a choice:

Run… or find out what St. Magnus is hiding.

But something in the hospital is watching them back.

With each clue, the danger grows.

And the deeper they dig, the more they realize the truth:

The experiments aren’t just changing animals…

They’re changing people.
