Twilight Zone Second Season

"This is one of the out-of-the-way places, the unvisited places, bleak, wasted, dying. This is a farmhouse, handmade, crude, a house without electricity or gas, a house untouched by progress. This is the woman who lives in the house, a woman who's been alone for many years, a strong, simple woman whose only problem up until this moment has been that of acquiring enough food to eat, a woman about to face terror which is even now coming at her from... the Twilight Zone."

The woman goes up to her roof to investigate a noise, and finds a flying saucer with two tiny, robot-like creatures emerging from it. The creatures torment the woman, until finally she grabs and batters one of the creatures into lifelessness. With an ax she destroys the saucer. Before the final creature is killed he sends a message to his home planet not to send any more ships to this planet. The lettering on the side of the saucer reads "U.S. Air Force."

"These are the invaders, the tiny beings from the tiny place called Earth, who would take the giant step across the sky to the question marks that sparkle and beckon from the vastness of the universe only to be imagined. The invaders, who found out that a one-way ticket to the stars beyond has the ultimate price tag. And we have just seen it entered in a ledger that covers all the transactions of the universe, a bill stamped 'paid in full,' and to be found... in the Twilight Zone."
