While attending a concert, Agent 86 Maxwell Smart (Don Adams) is called on his shoe-phone by the Chief (Edward Platt) and told to immediately go to CONTROL Headquarters.
It is then revealed that Mr. Big (Michael Dunn) of KAOS has overseen the kidnapping of Professor Dante (Vito Scotti) - the inventor of the Enthermo - and is demanding $100,000,000 or else he will use the weapon on all the major cities of the World.
Notably, in 1965, the year this episode came out, the New York Mets swept five doubleheaders - on 16 May, 24 May, 28 June, 5 July and 22 August - despite having an otherwise poor overall season record of 50-112.
As they are about to leave, Max notices a man watching them - likely from KAOS - and engages Agent 34 (stowed away in a locker) to implement Plan Y14, allowing 86 and 99 a smooth getaway.
While interviewing an associate of Professor Dante's at the lab from which he was kidnapped, K13 finds what at first appears to be a regular banana peel, but which 99 determines is made of rubber.
At 4:00 p.m. (it is currently 2:20 p.m.), the criminal organization promises, in full view of downtown Manhattan, to "destroy a great public figure" with the Enthermo, in order to prove the device's power.
In this episode, Maxwell Smart's car was a Sunbeam Tiger, that never left the studio lot, which is something Buck Henry makes mention of on the DVD's commentary in 2008.
Before the show was formally accepted by NBC, producer Leonard Stern had the foresight to film the iconic doors sequential scenes of the opening and closing credits in color that were used in all episodes, including the pilot.
