Four detectives die. But the gods, out of boredom, revive them as four monkeys. On one condition: that they solve the murder of a billionaire. The gods gave them a power: they can transform into existing people simply by knowing their names, allowing them to gather better information. But they must be careful not to be discovered. However, it won't be easy, because due to their past misdeeds, one of their five senses was taken away.
