I'm currently watching this on Netflix. Here's a partial summary of the first 12 episodes:

Girl trapped in ice.

Boy trapped in a tree.

People trapped in a storm.

Ship trapped in ice.

Couple trapped in a tar pit.

Couple trapped under wreckage.

Boy trapped under overturned vehicle.

People trapped in a cave.

Ship trapped on a precipice.

Mom and daughter trapped in a ravine.

The writers' meetings were basically:

(A) Who's getting trapped?

(B) What are they getting trapped in, on or under?

(C) In what contrived way will this occur?

(D) In what contrived way will they escape?
