Fox has bought a science-fiction drama called “Nod,” which is based on the novel of the same name by Adrian Barnes, reports Deadline.com.

The project, from 20th Century Fox TV and studio-based Chernin Co., is about how most people lose the ability to sleep. Fox has given the project a script commitment with penalty. Jason Richman of “Bad Company” will write the script.

According to Deadline, the project “revolves around Tanya and Paul, an ‘inter-somnial’ couple – she, Awakened and flourishing, and he, one of the remaining few who are still handicapped by the need for sleep. But when signs of deprivation start to show among the Awakened, the bonds of friendship and love get tested in unexpected ways — because if something seems too good to be true, it probably is.”
