The Fish with the Eyes of Gold (1974)

Derek, a handsome young Englishman, has recently moved to a Spanish seaside town. A lothario, Derek is quick to begin seducing the local women, only for a murderer to start picking them off one by one. Despite his protests of innocence, the police conclude that Derek is a sex maniac and responsible for the crimes. However, could another individual be behind the heinous killings? Remaining thematically and structurally aligned with its Italian forebears, Pedro Luis Ramírez' (School of Death) THE FISH WITH THE EYES OF GOLD (El pez de los ojos de oro) is an engrossing, twist-filled coastal caper with plenty of murders and other macabre surprises.
