Tom Whitney, well connected but a social derelict because of his weakness for drink, is released from the draft because of an old football Injury, but a policeman persuades him that he can still do his bit in the shipyards. He takes a job in the yard owned by the man to whose daughter he was engaged in happier times. Three German propagandists seek to foment a strike to delay the work, and largely through Tom's efforts the plan goes amiss and the strike is called off. Rehabilitated by work, the launching of The Liberty is a forecast of his own rebirth.
