‘Big Bang Theory’ Season 9 Episode 3 Spoilers: Leonard Kidnapped?

In tonight's Season 9 Episode 3 of CBS's The Big Bang Theory, we will find Raj and Howard planning Leonard's belated bachelor party. The entire gang including Raj (Kunal Nayyar), Howard (Simon Helberg), Leonard (Johnny Galecki) and even quirky Sheldon (Jim Parsons) will embark on a trip to Mexico. Raj and Howard decided the best way to get Leonard to Mexico is by kidnapping him. In good Big Bang fashion, the following events will likely stray far from original plans.

While the guys are on their way to Mexico, Penny (Kaley Cuoco) faces a dilemma with the girls. Bernadette (Melissa Rauch) and Amy (Mayim Bialik) try to convince her to tell her parents that she and Leonard eloped, although Penny's parents may not be too pleased. Returning to the show is Keith Carradine, who plays Penny's father.

As Penny tries to decide if she will tell her parents, she helps Amy get through her recent breakup with Sheldon. Amy decides that a break-up makeover is in order and both Bernadette and Penny are happy to help her.

The last season of Big Bang ended with Leonard and Penny impulsively driving to Las Vegas to get married. During the Season 9 opener, we saw the couple exchanging vows and then immediately after get into their first fight as a married couple. Leonard confessed to kissing another woman whom he still sees because she also works at the university.

In last week's episode, the two were able to make amends after facing their relationship insecurities. Penny was worried that she would never be smart enough for Leonard and he believed that she was too beautiful and completely out of his league.

Tonight's episode will be both filled with laughs and personal reflection as the characters face uncharted adventures in both honesty and fun.

The Big Bang Theory airs on Mondays at 8 p.m. on CBS.
