Long Live the Bride and Groom
¡Vivan los novios! (original)
Leo Pozas, native from Burgos and high bank clerk, arrives to a town on the Costa Brava, with his mother to marry Loli. Unexpectedly, Leo's mother died. This may mean the suspension of the wedding, a year of mourning and, perhaps, another relief, so that Leo and Loli hide the corpse of the old betrothal until after the wedding...
