In the high-stakes world of competitive poker, Flush follows a group of desperate strangers who are thrust together in an underground tournament where the ultimate prize is not money, but the chance to erase a devastating debt from their pasts. The series centers on Paloma Couto as a sharp-witted but haunted player who uses her mathematical genius to calculate odds, yet struggles to read the emotional tells of the people she once trusted. Alongside her, David Guenaga portrays a charismatic but morally ambiguous dealer who controls the game’s secret rules, while James Medleycott and Lauren Forman play a pair of siblings whose rivalry threatens to tear the entire competition apart. As the pressure mounts, Matt Pitcher, Sebastian Perez, and Selene Serra round out the ensemble as players hiding their own dangerous motives, each willing to bluff, betray, or fold for survival. This taut drama builds a tense atmosphere where every hand dealt could be a matter of life and death, exploring themes of redemption, trust, and the fine line between luck and skill. Viewers are drawn into a gripping narrative where the cards never lie, but the players always do.
