ACTION chronicles the lives of professional gamblers, bookies and oddsmakers throughout the 2018 NFL season following the Supreme Court decision to lift a ban on sports betting.

The series will culminate with the biggest gambling day of the year, Super Bowl Sunday.

The character-driven narrative delivers intimate access to a diverse cross-section of authentic and sometimes garrulous subjects within the sports gaming community, documenting the effects of legalization through their prisms.

The four-part series will premiere Sunday, March 24 at 8 p.m. ET/PT on SHOWTIME and peels back the curtain on a once taboo industry during its most critical juncture.
