When Oz's one-time protégé and now bitter rival, Henry Shaw, wins an important account away from OCP the two firms decide to settle the score with a game of "Capture the Flag".
Cam is excited to be chosen to go on a Leadership Conference with Veronica, but begins to worry that she may have ulterior motives. Back at Contra, Oz enlists Cash and Molly's help to find the treasure that Hurley, the old janitor, left buried somewhere on the premises.
When Molly discovers that she is about to be deported, the team stage a sham marriage to Cameron so that she can remain in the country - but Cash isn't happy with this idea. Meanwhile, the wedding forces Oz to reconsider his own marriage.
After she's banned from Contra's boys' night out, Veronica rallies the women for their own night on the town. But as Cameron worries about being the subject of the girls' gossip, the disappearance of a prized trophy forces Contra's men and women to join forces to find it.
Veronica believes her career is in jeopardy when longtime corporate rival Heather O'Brien decides to give Contra a makeover. Hoping to woo Heather's lovely assistant, Cameron tries to make his phony green card marriage to Molly appear legitimate.
Veronica's attempts to turn Contra into a more corporate workplace are met with resistance from the gang.
As Oz squares off in a fight to the finish with his longtime nemesis Henry Shaw, Cameron's marriage to Molly is threatened by the unexpected return of his ex-girlfriend and Contra's lock-picking expert, Melanie.
When his priceless Chewbacca costume from Star Wars is stolen, Molly's uncle Peter Mayhew turns to Contra to get it back. And though Oz plans to use the hefty reward to buy his company back from OCP, he still finds himself relying on Veronica for help.
