Netflix has released a new trailer for thriller Fair Play, highlighting exactly why some companies have policies against fraternization.

Fair Play follows couple Emily (Phoebe Dynevor) and Luke (Alden Ehrenreich), who are also co-workers at a cutthroat hedge fund. The duo keeps their romantic connection a secret due to it being in violation of company policy, which works out long enough for the pair to get engaged. However, their romance takes a dark turn when one of them receives a surprise promotion. Issues of power, ambition, and ego push them to turn on each other.

Fair Play arrives in select theatres on Sept. 29, then Oct. 6 on Netflix.
