You have several cases here in this story. First a cop is killed in a car crash when he was with a hooker, and our lead night shift cops try to find out who their colleague was, because they have no real name. Second, they have to face a robbery case, where gangsters pull a heist against a company where the boss had money in his safe. But after they had taken him as a hostage and taken the dol, they grab the boss's dog and fly away. Our cops lead this second investigation to get the hoods and the dog. But many holes remain in this case...
