Double collection of crime dramas directed by Francis Searle and Donovan Pedelty. In 'Emergency' (1962), Inspector Harris (Glyn Houston) races to find a matching donor for a young girl (Candy Pibworth) who has been knocked down by a truck. The trouble is there are only three possible matches for her rare blood type including a convicted killer, a professional fooballer and a scheming scientist, but will any of them be willing to help? In 'Landslide' (1937), a group of actors become trapped in a Welsh theatre after it is hit by a landslide. Entombed in the theatre, the group are forced to investigate when the cashier is found dead and their takings stolen.
