After attempting various romantic gestures and date nights, they decide to experiment sexually to try to reignite their passion. They have threesomes, visit a swingers club, and explore kinks and fetishes.
As they delve deeper into these sexual adventures, they begin to question if they are truly happy or just trying to escape the responsibilities of adulthood. The arrival of a young camp counselor, who catches the eye of both Sarah and David, leads to jealousy and tension in their relationship.
Eventually, they realize that they need to confront their issues head-on and work on their communication and trust. They end their sexual escapades and focus on rebuilding their marriage, learning that true intimacy doesn't come from physical pleasure alone.
