Charles “Chuck” Levine (Sandler) and Lawrence “Larry” Valentine (James) are veteran FDNY fire fighters. Chuck is a bachelor who is living single, while Larry is a widower trying to raise two children, one of whom is somewhat effeminate.
During a routine sweep of a burned building, a segment of floor collapses and Chuck almost dies. He is saved by Larry, who shields him from falling debris. As they awaken at a hospital later, Chuck vows to repay his debt in any way possible.
This event prompts Larry to realize the fact that death can come for him at any moment, but he has difficulties naming his children as primary beneficiaries in his life insurance due to the death of his wife. One of the ways suggested for him to do so is to get married. Inspired by a newspaper article about domestic partnerships, Larry asks Chuck to enter a civil union with him. Although at first Chuck declines, he is reminded of his debt to Larry and finally agrees. The two become domestic partners and Chuck becomes Larry’s primary beneficiary in the event of his death. Soon, city investigators arrive to inquire about their partnership, suspecting fraud. Larry and Chuck decide to enlist the help of a lawyer, Alex McDonough (Jessica Biel), who suggests that they become married. The pair then marries in Canada and move in together.
Unfortunately, with these revelations, the pair, along with all their fellow firefighters, are sent to prison, but they are quickly released after negotiating a deal to provide photos for an AIDS research benefit calendar. Two months later, Duncan and Alex’s brother, Kevin McDonough (Nick Swardson) are married in Canada at the same chapel as Larry and Chuck were. At the wedding party, Larry finally moves on after the death of his wife and talks to a new woman, while Alex reluctantly agrees to a dance with Chuck.
