Desperate for grandbabies and cursed with four wayward sons, Maggie Carson concocts a scheme to impersonate them in letters sent back east for mail order brides.
Rebecca Hart is the first ensnared, romanced by sweet words, poetry, and the promise of a new life. When she arrives in Topeka, she is eager to marry the man she thought she had come to admire, but the groom, Grant Carson, is nowhere to be found. It is his younger brother, Charlie, who greets her at the train station.
Charlie is appalled after discovering his mother's deception, yet jealous that Rebecca is meant for his older brother, who, in his estimation, does not deserve her. Grant reluctantly makes an effort to romance Rebecca, but his heart is elsewhere, as he is involved with a married woman in town. Rebecca and Charlie find themselves thrown together often, and a friendship emerges. An unexpected kiss confuses Rebecca, and she questions if it is Grant she really wants.
