Preston returns home one night to Emma. The conversation they have opens up the floodgates of every problem between them; all of the secrets they've kept from one another, everything they are too afraid to say. Preston suggests a solution—a drinking game. The rules of the game dictate that they pour six shots and ask each other honest, essential questions about the nature of their relationship. At any time, if someone wants to kill a topic or doesn't want to answer the question, they take a shot. If they finish all six shots, it means their relationship is beyond saving and they have to break up. Roulette asks us to consider whether human relationships are built on mutual effort or some uncontrollable, cosmic force.
