Relata la vida de Caleb, un adolescente del sur de Florida. En la víspera de su graduación de la secundaria, todo cambia cuando se expone al VIH. Mientras espera tres meses por sus resultados, encuentra el amor en lugares improbables.

When a mysterious man appears in a small town, unexplained miracles start to occur, changing the lives of everyone he meets. There's a mother whose five-year-old boy has leukemia, two doctors - one an atheist haunted by his past, the other a brilliant young oncologist who places all her hope in the power of modern medicine - and a blind pastor whose son hasn't spoken a single word in 38 years. All of them will be brought together by the presence of this stranger, who teaches them the true meaning of faith and hope.
