In His Brother's Place (1919)

Twins Nelson and J. Barrington Drake return home for the celebration of their parents' 50th wedding anniversary. Barrington is a wealthy oilman, but Nelson is a pastor in a small rural church, who is struggling to increase his ever-shrinking flock, Barrington tells him that his problem could be solved with the right type of salesmanship, and proceeds to map out a plan to do just that. However, a case of mistaken identity--and a scheme by two of the church's deacons to take over all of the church property--throws a wrench into his plans.
