You and a group of friends are trapped in a cave, which will soon fill with water from the incoming tide. You have minutes to live and there is only one small hole where you can escape.

Your friend Jane, who is pregnant, decided she was going to be the leader and get the group to safety. But she is now lodged herself in the hole and she can’t budge. Because she is stuck, no one else can escape. When the water seeps in, she will survive because her head is out, but everyone else is doomed.

You have a single stick of dynamite, which will blow up a human being but not open another entrance.
