It was getting dark as you were returning home from work. It was a long walk for you as you had missed the last bus to get back home. As you were passing by this locked house you heard a cry from inside. You easily figured out that someone was trapped inside the house and he could be in trouble. You decide to go inside the house to rescue the poor fellow. You know very well that this will not be easy rescuing the person has become your priority and you are not someone who will leave without doing something. Good luck!
