Photo Flash: Promo Shots for NBC's WELCOME TO THE FAMILY

NBC has debuted the promotional cast shots for its new comedy WELCOME TO THE FAMILY, starring Mike O'Malley, Mary McCormack, Ricardo Chavira, Justina Machado and more. Check them out below!

Dan Yoder (Mike O'Malley, "Glee," "My Name Is Earl") and wife, Caroline (Mary McCormack, "In Plain Sight," "The West Wing"), think they finally have it made. Their daughter, Molly (Ella Rae Peck, "Deception," "Gossip Girl") - not the most diligent of students - has managed to graduate from high school and has been accepted to college. The proud parents are looking forward to an empty nest and are breathing a heavy sigh of relief.

Across town, Molly's secret boyfriend, Junior Hernandez (Joseph Haro, "Glee," "Awkward"), is graduating from his high school with top honors and has plans to go to Stanford. Parents Miguel (Ricardo A. Chavira, "Desperate Housewives") and Lisette (Justina Machado, "Six Feet Under," "ER"), who also have a younger son, Demetrio (Fabrizio Guido, "World War Z"), are bursting with pride. Everything seems like it is falling into place for them, but unbeknownst to both families, Molly and Junior are about to become parents themselves.

Once the teens break the big news, these two very different families are thrown together, which goes anything but smoothly... and the news that Molly and Junior are engaged to be married doesn't exactly make things better.

Dan and Miguel have the most difficult time adjusting to their new situation (and each other), while Caroline and Lisette take a softer approach to getting to know one another. When each of the parents realizes the kids are serious about making a life together, the adults Exhale and begin to come to terms with this new blended family. Clearly, it will take understanding, humor, love and patience to make it all work.

Welcome To The Family premieres Oct. 3 on NBC.
