After being away for fifteen years, Seth Caplan comes home to Chicago to care for his mother and to partner with a small start-up tech company. He and Kyle meet after Kyleâs collision with a childâs sidewalk toy, and they hit it off. Kyle wants to get back into running, and Seth becomes his guide. As they get to know each other, they start seeing each other beyond their three-times-a-week runs. But Sethâs revelation of the dark reason why he left his career in California sends the relationship into a tailspin and leaves both men running blind.
