According to his plan, anyone can become a police officer after undertaking a brief training session. To sabotage his plan, the chief of police picks the most ineffective and brainless of the applicants, hoping to give a fruitless start and abort the project entirely. Things don't go according to his plan, when with luck and courage, these men who are futile in every other aspect of their lives, finish the training and go on to catch long-time sought-after criminals, causing plenty of havoc along the way.
