Tidal and Sprint are releasing an exclusive film starring Mahershala Ali, Lupita Nyong’o, and Danny Glover called 4:44. Tidal aired an ad during the NBA finals revealing the project, which has been teased around the web through enigmatic ads.

Few other details have been provided about 4:44. The film is NC-17; the moody black-and-white trailer features Mahershala Ali wailing on a punching bag in a slow-mo training montage.

At the Oscars earlier this year, Ali took home the award for Best Supporting Actor for his performance in Moonlight.

The partnership with Sprint on the film is unsurprising, given the company bought a 33 percent stake in Tidal in January. At the time, Sprint said the deal would give its subscribers “unlimited access to exclusive artist content not available anywhere else.”
