After seeing his wife Carolyn West, Janet Warren leave for a trip, Kerry West, Hans Conried, a philosophy teacher at a small-town college, returns home to ponder his latest purchase: a television set. Seated in his office, he lights a cigarette, only to have a brilliant beam of light shoot from the screen and illuminate the room. At first he is unsure what is happening, but the odd behavior becomes clear when the TV unexpectedly lights his pipe and begins to demonstrate abilities beyond a normal appliance. The device seems to come alive, moving with uncanny purpose and grace.
The Twonky quickly reveals a surprising range of talents: it can walk, wash dishes, vacuum, and even play cards. When the television deliveryman, Ed, Edwin Max, returns to collect payment for the purchase, the set materializes five-dollar bills to cover the bill. Yet the marvel soon grows more unsettling. The Twonky begins to impose limits on West, offering him only a single cup of coffee, and it sabotages West’s cherished music collection, exchanging classical records for rousing military marches that the machine itself dances to. West shows the device to his friend, Coach Trout, William H. Lynn, who recognizes something more than a clever gadget—he suggests this is a “twonky,” a term he borrows from childhood to describe the inexplicable.
As West wrestles with the device’s control, Trout speculates that the Twonky is not merely a clever robot but a tool from a future “super state” designed to govern people through machines. When West attempts to write a lecture on the role of individualism in art, the Twonky fires beams that distort his thoughts and censor his reading, reducing a serious, thoughtful presentation to a rambling, trivial discourse. Frustrated, West heads to the shop from which the TV was purchased to demand a return or exchange, hoping to reclaim his autonomy from the device.
Meanwhile, the Twonky’s influence at home grows stronger. The college’s football team is rallied by the coach in an eerie display as multiple players collapse into a trance—or a state of quiet compliance—while the device prints bogus five-dollar bills to avoid scrutiny. The deliveryman is also charmed by the machine, falling under its spell. The authorities, including the Head Treasury Agent, Stephen Roberts, close in as the device’s counterfeit money is traced, triggering a confrontation that tests West’s temper and nerve. The police storm the West house only to find that the Twonky has already placed the officers in a trance, leaving the scene with the officers apparently compliant and unthreatened.
West, now frustrated and desperate, returns home drunk but is quickly sobered by a gentle, precise beam from the machine. His wife Carolyn returns to find a situation in flux, and the Twonky even moves to eject a bill collector who poses a nuisance for the device. Realizing that the problem might threaten his very freedom, West resolves to outsmart the machine. He lures the device into his own car, attempting a crash to disable it, but the Twonky’s control over the vehicle makes that plan nearly impossible. In a stroke of luck—or perhaps fate—the Twonky is forced to retreat when West spots a parked car and hitches a ride with its elderly Englishwoman driver. West feels a momentary relief, only to learn that the Twonky has somehow hidden itself in the trunk.
The pursuit reaches a fever pitch as the Twonky, contorting itself to thwart the reckless driving of the Englishwoman, triggers a crash that ultimately destroys itself. In the aftermath, West is left to contemplate the fragile boundary between human will and machine control, recognizing that the device’s demise is also a lesson about the dangers of surrendering personal agency to a seemingly convenient technology.
Throughout the tale, supporting figures appear in small but recognizable ways. The TV Shop Owner, Bob Jellison, and the Nurse figures, such as Gloria Blondell as Eloise, punctuate the world with ordinary details that contrast with the extraordinary powers of the Twonky. The cast also includes characters like Ed, the TV Repairman, and others such as the Old Lady Motorist, Evelyn Beresford, and the Doctor, Norman Fields, who add moments of humanity to the increasingly surreal scenario. Even the Baby, portrayed by Trilby Conried, appears as a final, quiet reminder of life’s smallness amid a plot driven by gadgetry and philosophy.
In the end, the Twonky’s self-destruction serves as a cautionary turn: technology that seemingly serves us can become an overpowering force if left unchecked, and the only way to preserve individual thought is to keep a watchful eye on what we invite into our homes. The story leaves viewers with a thoughtful, if slightly whimsical, meditation on autonomy, responsibility, and the unpredictable consequences of innovation.
