Nothing but lies (1920)

George Cross, a junior partner in the advertising agency of Nigh and Cross, goes to his office one evening to get a plate for a newspaper and surprises Allan Nigh, his partner's son, who has been distributing a leaflet exposing the lies of the advertising firm. Rosie, a member of the "Truth Society" to which Allan belongs, is hiding in the next room. George sends Allan to the newspaper office and then discovers Rosie. Shortly thereafter, Nigh and his daughter Ann, who is also Allan's sweetheart, arrive and George lies his way out of a compromising situation. Soon after, a detective arrives to investigate a front-page exposé on the circulars that Allan has written. When the advertisers realize that the exposé is actually the best campaign ever conceived, the supposed detective offers Allan a tremendous salary to write ads for him, Rosie reveals herself as a reporter from the Journal and Allan and Ann reconcile.
