Bulldog Drummond (John Howard) is on the trail of some stolen newly invented high explosive with the help of his fiance (Louise Campbell), trusty butler (E E Clive) and his bumbling friend (Reginald Denny) and his girlfriend (Nydia Westman). The action takes place on the way to Drummond's wedding in Switzerland and so is filmed in cars, trains and a boat. The plot is pretty standard and Louise Campbell and Nydia Westman are distracting as they keep fainting. John Barrymore is top billed, but has only a comparatively small part as the policeman.
