L'Ile Du Bout Du Monde on AllMovie

A so-so drama with uneven acting, this is a tale of three women and one man trapped on a deserted island in World War II after a shipwreck. Christian Marquand is Patrick, the lone man who cannot but develop a relationship with all three women. Their fates are not what might be expected, as the women slowly reveal their true natures. One tries to get to another island to find help, and one turns out to be pathologically homicidal. She kills the only other woman, leaving two choices for her murderous inclination -- herself or Patrick or both.
