The synopsis reads: "Brilliant Sheldon is confronted by a mystery of the universe he cannot unravel: when a woman wants time apart to think, exactly how much time does that mean, and is there any way to hurry the process along? In Las Vegas, Penny and Leonard march closer to marching down the aisle, but has Penny gotten over Leonard's infidelity? And if so, will he do anything to un-get her over it?"

The previous season ended with a cliffhanger, with Amy breaking up with Sheldon, only to be revealed in the last moments that he was planning to propose to her. Leonard and Penny were headed to Las Vegas to tie the knot, but after he told her about kissing another woman during the North Sea expedition, Penny was no longer sure about marrying him, according to the International Business Times.

Meanwhile, it has been revealed that "The Big Bang Theory" season 9 will pick up a few hours after where the season 8 finale left off, Hollywood Hills has learned.

"Big Bang Theory" Season 9 premieres on Monday night, Sept. 21, on CBS.
