The Stronger Vow is a 1919 American silent melodrama film directed by Reginald Barker and distributed by Samuel Goldwyn.

[1] As described in a film magazine,[3] the film deals with the "oath of blood" Dolores de Cordova (Farrar) takes when her brother is murdered during a carnival to kill the murderer with her own hand and the vow she later takes upon marrying Juan Estudillo (Sills).

Dolores believes her cousin Pedro Toral (Santschi), who is the real murder, when he accuses Juan just after the wedding dinner, because there long had been a feud between the two Spanish families.

Pedro sets a trap for the husband, but Juan is connected with the secret police, and arranges for a raid on the Apache den.

This clears Juan of the false accusation and allows Dolores to keep the stronger vow made at the altar.
