Two sisters join the first female professional baseball league and struggle to help it succeed amidst their own growing rivalry.

Rich Mr. Dashwood dies, leaving his second wife and her three daughters poor by the rules of inheritance. The two eldest daughters are the titular opposites.

After an outlaw named Tom Chaney (Josh Brolin) murders her father, feisty 14-year-old farm girl Mattie Ross (Hailee Steinfeld) hires Rooster Cogburn (Jeff Bridges), a boozy, trigger-happy lawman, to help her find Chaney and avenge her father. The bickering duo are not alone in their quest, for a Texas Ranger named LaBoeuf (Matt Damon) is also tracking Chaney for reasons of his own. Together the unlikely trio ventures into hostile territory to dispense some Old West justice.
