Six men and three women - against the sea, and each other!

During World War II, a small group of survivors is stranded in a lifeboat together after the ship they were traveling on is destroyed by a German U-boat.
Lifeboat keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
