The Invisible Power (1921)

Ex-convict Sid Chambers, while lodging with the Millers, meets schoolteacher Laura Chadwick, and in spite of his record she believes in him. They are married, move to the city, and are happy. Shadwell, the detective who sent Chambers to prison, tries to obtain information from him regarding a former friend and gang member, Bob Drake, who has committed a robbery; and refusing to cooperate, Chambers is sent to prison again on another charge. Meanwhile, Laura's child is born, and fearing that it will develop criminal instincts she gives it up for adoption. When Chambers is released, he vows to kill Shadwell, and Laura, in her effort to warn him, finds her child in Shadwell's home. Touched by her grief, Shadwell arranges to give Chambers his freedom, and the couple is reunited.
