Directed by Gil Junger, the film is written by Tom J. Astle and Matt Ember, based upon concepts created for the original Get Smart TV series by Mel Brooks and Buck Henry.

A new "Optical Camouflage Technology" (OCT) or invisibility cloak is developed by Bruce and Lloyd in the USA, but has a short battery life, lasting only 6 minutes, which they hope to later turn into over 24 hours.

Isabella meets with President Krause, who tells her the organization KAOS has offered $50 million for the OCT, but the President is more interested in Bruce and Lloyd, the principal developers of the OCT. Isabella wants to trade Bruce and Lloyd for the scientists of Maraguay, one of whom is her father.

Bruce and Lloyd discover that polarized sunglasses act as an anti-OCT to view the invisibility cloak.

The President finds and threatens them with a gun, but Lloyd tases him and he is killed when an elk head falls on him.
