Traffic Light follows the lives and romantic entanglements of three lifelong male friends who find themselves at completely different milestones in their relationships. Symbolized like a traffic light, one is newly married and feeling the sudden, overwhelming constraints of domestic life, another is in a long-term relationship and debating whether to take the plunge into marriage, and the third is happily single and enjoying the chaotic freedom of bachelorhood. As they navigate the daily absurdities of career, romance, and aging, the trio frequently meet at street corners to share advice, vent, and realize that love is never a simple green, yellow, or red.
