I Now Pronounce You Chuck And Larry features Adam Sandler and Kevin James as Chuck Levine and Larry Valentine; two firefighters who are the pride of their fire station: two guy's guys always side-by-side and willing to do anything for each other. Grateful Chuck owes Larry for saving his life in a fire, and Larry calls in that favor big time when civic red tape prevents him from naming his own two kids as his life insurance beneficiaries. But when an overzealous, spot-checking bureaucrat becomes suspicious, the new couple's arrangement becomes a citywide issue and goes from confidential to front-page news. Forced to improvise as love-struck newlyweds, Chuck and Larry must now fumble through a hilarious charade of domestic bliss under one roof. After surviving their mandatory honeymoon and dodging the threat of exposure, the well-intentioned con men discover that sticking together in your time of need is what truly makes a family.
