The Danger Signal (1926) is a Drama film that follows a recently widowed and destitute young mother (Jane Novak) appeals to her wealthy and heartless father-in-law (Robert Edeson) for financial aid. Instead, he convinces her to hand over her new baby to his care so that the child will be brought up with "everything money can buy." Unbeknownst to the grandfather, we learn that there are twin sons and our heroine keeps one baby to raise herself. The narrative jumps ahead to the boy's twenty-first birthday and we see what's become of them.
