“Lifeline” is a half-hour series set in the near future, focusing on a relatively obscure life insurance company with a unique twist: it dispatches its agents 33 days into the future to avert accidental deaths of its policyholders. The story centers on Conner Hooks (played by Gilford), the company’s top agent, who has an impeccable record of successful interventions. However, his streak is challenged when he faces his most personal mission yet. After sixteen-year-old Norah (portrayed by Park) becomes an orphan under his watch, Conner vows to safeguard her, even if it means risking his career at Lifeline or his own life.
