A still from CBS’s “Under the Dome.” (CBS)

NBC is taking a poke at CBS’s summer Stephen King series, “Under the Dome,” by scheduling its acquired sci-fi drama, “Siberia,” in the same time slot.

“Dome” will debut June 24 at 10 p.m.; “Siberia” will launch the following Monday.

“The Dome” involves an impenetrable dome that falls kerplunk over a picturesque town in Maine. “Siberia” is set in the remote Siberian territory of Tunguska, site of the “Tunguska event” of 1908, in which it is believed an air-burst, caused by a meteoroid or comet exploding in the atmosphere, flattened about 80 million trees.

More than 100 years later, 16 reality-TV competition-series contestants — chosen for reasons other than their education — are sent there to Tunguska seeking 15 minutes of fame, with no knowledge of the location’s significance. When a contestant is badly injured and no medical help shows up, they realize the incident wasn’t a show “challenge” gone wrong.
