Egoism (1964)

Unwilling to shed a single tear at her father's funeral, free-spirited Maria, a young woman who knows how to stand up for herself, plans her next move. First, receiving a substantial inheritance is a step in the right direction. But making a legacy last requires a lot more than luck and good looks. With this in mind, the blonde heiress puts into action a devious scheme--a foolproof plan that will set Maria free from her sister and her money-grubbing fiancé, once and for all. In everyone's eyes, Maria is nothing but an arrogant egotist who stops at nothing to get what she wants. However, when a whirlwind romance imperils her dream, Maria will have no choice but to surrender to the power of passion.
