After seeing his wife (Janet Warren) off on her trip, Kerry West (Hans Conried), a philosophy teacher at a small-town college goes inside his home to contemplate his new purchase: a television set.

West soon discovers that the television can walk and perform a variety of functions, including dishwashing, vacuuming, and card-playing.

After tending to the coach, West attempts to write a lecture on the role of individualism in art, but the Twonky hits him with beams that alter his thoughts and censors his reading.

As the now-fixed Trout attempts to leave, police storm into the house in response to a call made by the device seeking female companionship for West, followed by Treasury men tracking down the bogus $5 bills manufactured by the set.

Luring the device into his car, he attempts to crash it by a variety of means but is frustrated by the Twonky’s ability to control the vehicle.

Spotting a vehicle parked alongside the road, West pulls over and abandons his car, hitching a ride from the other driver, an elderly Englishwoman.

The Twonky was based on the 1942 short story by established science fiction writers Henry Kuttner and C. L. Moore, writing under their joint pseudonym Lewis Padgett.
