Plot

Minnesotans Scott and his bride Kristin are having their wedding in Phoenix. During the wedding, Kristin is put off by the obnoxious behavior of Scott's best man Lumpy. Lumpy gets extremely drunk and more annoying to the guests until he is cut off from the bar by Scott. Returning to his hotel room, Lumpy continues drinking and carrying on until he accidentally falls and cracks his skull before passing out. He awakens a short time later disoriented and bleeding, and gets himself locked out of the hotel. Wandering into the brush, Lumpy passes out and dies on top of a cactus. He is found the next morning and Scott and Kristin are informed. Since Lumpy was his best friend, Scott feels it is his duty to arrange for Lumpy to be returned to Minnesota for a funeral. Kristin is upset that her honeymoon will be postponed, but she supports Scott in his decision. After arranging transport for the body, they return to Minneapolis to contact Lumpy's friends and plan the funeral.
