The plot for "The Big Bang Theory" season 10's premiere episode has been leaked online, and will be titled "The Conjugal Conjecture." Fans had a lot of questions when the previous season ended last May, which have been answered ahead of its premiere on Sept. 19.
"Alfred and Mary share an evening together, everyone deals with an awkward morning the next day. Also, Penny's family arrives for the wedding ceremony, including her mother, Susan (Katey Sagal), and her drug dealing brother, Randall (Jack McBrayer)," reads the official logline for the season premiere.
According to the leak, the show will open with Leonard (Johnny Galecki) and Penny (Kaley Cuoco) in bed, Sheldon (Jim Parsons) in his room. Sheldon is worried that Leonard's father might be doing something to her mother.
The next day, as Penny is about to leave to pick her family from the airport, she reminds her husband and Sheldon to act normal when Beverly (Christine Baranski) arrives. She also reminds the two not to mention a word about Alfred (Johnny Galecki) and Mary (Laurie Metcalf) activity the night before. Beverly suddenly walks into the apartment and does not want to attend the wedding ceremony anymore.
Meanwhile, Penny has picked up her mother and brother, and goes back to the apartment. Penny's mother is worried about the things that Leonard's parents might think about their daughter-in-law's family.
The tension is high when everybody is back in the apartment. They are discussing who goes with whom when Amy (Mayim Bialik) arrives in her bridesmaids dress and says,"Who's ready for a wedding!."
Next is a scene where Leonard's parents meet Penny's family. A pretaped scene of the wedding ceremony follows this, where Amy plays the harp while Bernadette (Melissa Raunch) officiates the event. Before Bernadette announces the new couple, Sheldon walks up to the front and tells Leonard how much he loves him.
"The Big Bang Theory" season 10 will premiere on Sept. 19 on CBS Network.
