Best Man Wins is a 1948 American historical drama film directed by John Sturges and starring Edgar Buchanan, Anna Lee and Robert Shayne.
The year is 1853 when inveterate gambler Jim Smiley returns to his hometown of Dawson's Landing in Missouri after being away for a decade from his wife and son.
Instead Bob's dog wins the race, and Jim feels guilty over having lied to Nancy and let his son down by not believing in him.
The challenge turns into a bet, where Jim stakes $1,000 that his frog will beat his friend Amos' leaper, Martha Washington.
Jim layer confesses to Nancy about the bet on the previous dog race, but she is still happy about his new honest behaviour and agrees to remarry him anyway.
