Hoping to give an audience boost to Cinemax’s new drama “The Knick,” parent company HBO will be airing the first three episodes of the historical medical drama on Labor Day.

Starring Clive Owen and directed by Steven Soderbergh, “The Knick” is set in turn-of-the-last-century New York City and tells the story of the surgeons, nurses and staff at The Knickerbocker Hospital who push the boundaries of medicine in a time of astonishingly high mortality rates.

Cinemax has a lot riding on the project, which was renewed for as second season ahead of its first season bow. While the premiere episode did not attract many viewers for its original viewing on Aug. 8, it did gain an audience through repeat airings that weekend. Cinemax also offered a free online streaming of the first episode.

The HBO marathon of “The Knick” beings at 8 p.m. on Sept. 1. The show will return to Cinemax to air its fourth episode at 10 p.m. Sept. 5.
