Across the Dead-Line is a lost[1] 1922 American silent northwoods drama film directed by Jack Conway and starring Frank Mayo.

[2][3] As described in a film magazine,[4] after Enoch Kidder (Simpson) discovers his son John (Mayo) in his brother Aaron's (Lucas) saloon, he lays a line down the center of the main street of the rough mining town and separating the brothers' houses, and tells Aaron that he will kill him if he ever steps across it.

Aaron wants to discredit John's honesty and attempts to blackmail him and kidnap the woman, now known as Ruth (Malone).

Warned of Aaron's plan, John takes Ruth to a lodge high in the mountains.

Ruth's memory is restored, and there is a happy ending when her bogus husband is exposed.
