When a man crashes down a sinkhole after some road rage, Horatio and Frank uncover a bank vault underground, which leads to the suspicion of a bank robbery. They also find the body of a woman that they believe was in on the robbery but left for dead when the car came crashing down. Delko talks to the bank manager, who denies that anyone can break in to the vault, especially the woman. Meanwhile, the team gets suspicions that the workers who transport oranges from factories to stores hide cocaine in special compartments inside the crates.
