In His Brother's Place (1919)

"They were twins but you wouldn't know it. One was a successful business man. See what happened when the financier took the preacher's place."

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.
