TV reporter Kate Bradley arrives in Manhattan ready to take on a challenging new position as a national news correspondent. When a massive power outage plunges New York City into darkness, the disaster she expected to cover takes an unexpected turn. Someone is leaving thousands of mysterious gifts throughout the city, and the only clue to the giver's identity is the occasional note from "A Stranger." Together with handsome TV series host Scott Jameson, Kate must make sense of these random generous acts, which quickly escalate in scale and capture the attention of viewers across the country. In early-morning stakeouts and late-night surveillance, they crisscross the city hunting down leads, but the elusive Stranger is always one step ahead. Menacing letters and videos addressed to Kate threaten to derail the investigation, but she's determined to uncover the identity of the benefactor. The closer Kate gets to the truth, the more clearly she sees that even the smallest act of generosity can bring about powerful change. And it just may take her own selfless act of kindness to solve the feel-good mystery of the year
