Switched at Birth (TV)

On the same night, Milford maternity delivers Morgan, businessman James and Sarah's son, and Linda's boy Luke Wells, whose father Darryl Moncton left town never having wanted kids, so they will live with her parents, but a nurse switches the babies' name tags. Two years later, Darryl returns but denies paternity; he accepts a DNA test if she promises to leave his life anyway, revealing neither is Luke's biological parent. What must happen now? - IMDb
