Four Christmases

Brad (Vince Vaughn) and Kate (Reese Witherspoon) are an upscale San Francisco couple. Both come from dysfunctional families, with divorced parents and obnoxious siblings with out-of-control kids, so they disdain the idea of getting married or having kids. They try to avoid their families at Christmas by traveling abroad and pretending to be going there to do charity work. The third Christmas of their relationship, they plan to go to Fiji, but get trapped at San Francisco International Airport by a fog bank that cancels every outbound flight; they're also interviewed by a news crew, alerting their families that they're stuck at home for the holidays.
