The episode centres on Gwen Cooper (Eve Myles) working her first case with the alien hunters Torchwood in Cardiff, when she lets loose a purple alien gas that survives on the energy of orgasms. Over the course of the episode, the team hunt for Carys before the gas kills her.
Originally entitled "New Girl", the episode was written to interpret Gwen's "first day in hell". On the sex gas, series creator Russell T Davies stated "when we're launching a new adult science fiction drama, it's kind of inevitable you're going to do the sex monster". The episode was filmed during a three- to four-week period in May 2006, with much of it filmed before the first episode in the same production block. "Day One" was originally seen by 2.3 million viewers, making it one of the highest-rated BBC Three broadcasts of all time, but was met with generally mixed reviews.
