Where can I watch this?

Two brothers - one virtuous, one feckless - are in love with the same woman. She falls for Brother Wrong, carrying a torch for him even after he deserts her. But Brother Right remains steadfast and available. What's unusual here is why the bad brother pulls his disappearing act. Mark walks out on wife Dianne after learning that the baby they're expecting has severe genetic abnormalities. Dianne is nonetheless determined to bear her child, with support from her mother and Mark's brother David, a pediatrician whose love for Dianne is unspoken but obvious. How do they cope with the challenges of raising this little girl named Julia?
