Today is a holiday for George. He has planned to go for a movie with his friend Tom. There is a trouble for George in coming out of the house. Outside the house a ferocious wolf is awaiting him. Though he is courageous enough it is not time to prove his mettle. He has a dog which would come to his aid when he is in trouble. Release the dog from the cage. That will chase the wolf away. Find out the key through which you can open the cage. You may not be able to find out the key unless you solve puzzles. Open the cage as soon as possible so that George would reach the theatre on time.
