Frank Diego is compelled to use public transportation for the first time. But his walking, busing, and trolleying through San Diego becomes a zig-zagged comedy of errors as he encounters odd, colorful characters along the way. Frank's daylong journey prompts flashbacks to events that have shaped his bicultural identity (half Mexican and half white) and account for his recently failed relationship. By the time Frank makes it to the beach to meet his so-called girlfriend, the journey has transformed his perspective and led him to a life-changing decision.
