The episode was directed by Ryan Case and written by Paul Corrigan & Brad Walsh & Bill Wrubel.
Gloria believes that Joe may be too "white" for her family so she takes him in the sun before the photo, leading to a bad sunburn and a worse solution from Manny.
Claire (Julie Bowen) asks Phil (Ty Burrell) to wait for the repairman of the washing machine since the rest of the family will be absent from home.
Phil tells her not to worry but when he receives a call from a discman who informs him that a song (which reminisces him about his first sexual experience) has been re-edited, he rushes to the store to buy it.
Alex (Ariel Winter), who has an AP Biology essay assignment about narcolepsy, notices that her dad constantly falls asleep and knowing that this might be a sign of guilt, she forces him to tell the truth on their way to Jay's (Ed O'Neill) house.
Meanwhile, Luke's (Nolan Gould) black shirt needs to be washed as Gloria (Sofía Vergara) decides to organize a new family portrait since Joe's birth.
Claire accuses Cameron (Eric Stonestreet) of being too snobby for not getting Lily (Aubrey Anderson-Emmons) to wear her girls' old clothes that she gives to him.
Before the portrait, Gloria notices that Joe's face is too "white" and she can not send a picture to her family in Colombia of her son that does not look even a little bit Colombian.
Manny (Rico Rodriguez) saves the day by giving Joe make-up which makes him wear Colombia's flag's colors on his face that hide the sunburn.
Club rated the episode with a C− and wrote, "What makes 'Sleeper' especially disappointing is how it diminishes Phil, Modern Family's most consistently written character, by putting him in an aimless, unfunny plot that even Ty Burrell couldn't save.".
