A dishy drama about two teens who learn they were mistakenly switched at birth was bound to be a hit. Tonight, cynical Bay (Vanessa Marano) presses her single birth mom to reveal her "real" father. Meanwhile, deaf Daphne (Katie Leclerc) is reluctant to bond with her own birth parents. While not every plot enthralls, Birth tugs at the heart with its themes of love, trust and self-truth.
