Allen and Janice Lowry (John Heard, Patricia Kalember) discover that their only child Erica (Jennifer Brox) has leukemia, and needs an immediate bone-marrow transplant. Unfortunately, neither parent completely matches Erica's DNA; if only she had a sibling who was willing to be a donor. Just when the situation is at its bleakest, who should arrive at the Lowry's doorstep but 16-year-old Robbie (Trever O'Brien), who claims to be Alan's illegitimate son. This turns out to be true--and sadly, it is also true that Robbie's embittered mother Debbie (Sherry Hursey) flatly refuses to allow her son to be tested as a donor. It is up to Monica (Roma Downey) and the angels to not only melt Debbie's hard heart, but also save the Lowrys' now-fractured marriage. ~ Hal Erickson, Rovi
