M Squad
Lt. Frank Ballinger is a no-nonsense plain clothes cop in the elite M Squad Division. The Squad's task is to root out organised crime and corruption in America's Second City, Chicago.

When an "electronic brain" worth $2,000,000 is stolen and held for ransom of $300,000, Captain Grey and Lieutenant Ballinger devise an elaborate ruse that they hope will lead them to the computer and the thieves.
