What is the secret hidden in the apartment complex?

One fateful summer, a group of elementary school kids set adrift on an abandoned apartment building must look within themselves to find a way back home.
Drifting Home keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder, compressing memory, grief, friendship, survival, growth.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
