Hall Pass

Rick (Owen Wilson) and Fred (Jason Sudeikis) are best friends as are their wives, Maggie (Jenna Fischer) and Grace (Christina Applegate). They are both unhappy with their sex lives and missing the old days when they were single. Realizing this, their wives decide to give them a "hall pass": A week off from marriage, in which they can have sex with other women. They are skeptical at first, but ultimately accept the offers and try to pick up women with their friends Gary (Stephen Merchant), Flats (J.B. Smoove), and Hoghead (Larry Joe Campbell). Maggie and Grace spend Rick's and Fred's Hall Pass Week at Maggie's parents' house in Cape Cod, where Grace flirts with athlete Gerry (Tyler Hoechlin), saying that if their husbands have hall passes, so should they.With their wives and children away, Fred and Rick check into a motel and prepare for their Hall Pass Week.

They decide to get drunk in order to loosen up, but go too far and wind up getting into a fight with other customers. They spend Day Four at the hotel, suffering from a hangover.On Day Five, Rick goes to a local coffee shop, where he flirts with an attractive waitress called Leigh (Nicky Whelan), much to the annoyance of her co-worker Brent, who insults Rick. When Rick answers him back, Leigh is impressed and tells Rick that they might see each other at the local gym they both attend. They later meet there, and Leigh invites Rick for a beer after they work out. Rick decides to go to a sauna instead, but falls asleep and stays there too long, getting burned and being forced to accept the help of two naked men to leave, much to his dismay. Meanwhile, Grace and Gerry get closer, while Maggie finds herself attracted to Gerry's coach.On Day Six, Rick and Fred go to a bar called Enter the Dragon with their friend Coakley (Richard Jenkins), where Rick meets his children's babysitter Paige (Alexandra Daddario), who has just turned 21 and is with her aunt.
