The Secret of the Empty Box - A giant box appears out of nowhere. The Flash realizes it's a trick, designed to divert attention while the real crime is happening elsewhere. As he searches for clues, he realizes that the situation is worse than he thought: there are actually three crimes to stop, all without arousing the suspicians of Iris.
The Coldest Man on Earth - Len Snart has developed a weapon capable of freezing anything. He uses it to go on a crime spree, leaving Barry Allen trying to gain traction and ground against the unusual foe.
