Travelers (1992)

A young woman's wedding becomes a ritual of mourning when her sister and family die in an auto accident on the way to the wedding. The sisters' mother refuses to accept her daughter's death, and in the midst of wedding guests and mourners, including the drivers of the truck that caused the accident, she orders the wedding to take place. But how can the daughter marry in the midst of a wake and without the family's traditional mirror, which the sister was bringing to the service?
