Oliver McCall vs. Larry Holmes, billed as "Burden of Proof", was a professional boxing match contested on April 8, 1995 for the WBC Heavyweight Championship. After Oliver McCall stunned Lennox Lewis in the second round to become WBC Heavyweight Champion, he turned down a $10 million offer from Lewis for an immediate rematch. Instead he agreed to fight 46 year old former WBC, IBF and lineal heavyweight champion Larry Holmes, who was making his fourth attempt at regaining a heavyweight title after losing to Michael Spinks in 1985. Each of his previous three attempts (against Spinks in 1986 in a rematch, against Mike Tyson in 1988, and against Evander Holyfield in 1992) ended in defeat, although he went the distance in two of the three fights.

Ollie falls in love with a woman. When he discovers she's already married, he unsuccessfully attempts suicide but he and Stan then decide to join the Foreign Legion to get away from their troubles. When they’re arrested for soon trying to desert the Legion—they escape a firing squad by stealing an aircraft.

Barbershop owners Stan and Ollie answer an ad in the newspaper from a wealthy widow looking for a husband. Ollie only mails in his response and is invited to the widow's mansion. Stan discovers his unmailed letter and insists on tagging along. At the mansion, the widow's creepy butler informs them that the woman is crazy. She was once jilted by an Oliver and now her hobby is marrying Olivers and then slitting their throats. Now the boys must figure out how to escape.
