Four Sided Triangle (1953) • Discape

She lived two amazing lives under his evil spell.

Four Sided Triangle (1953) follows two young scientists who build a pioneering reproducer machine capable of duplicating matter at the atomic level. When one of them, unable to accept unreturned love, uses the device to create a duplicate of the woman he desires, the experiment ignites a painful conflict of identity, emotion, and moral responsibility. This science-fiction melodrama blends speculative ambition and romantic tension in a tragic study of longing and ethical transgression.
