Luna Sterling's lover, Julian Sutton, died. She discovers Leo Landon is a spitting image of Julian. This resemblance leads her to marry Leo. Leo, with his mistress Nancy Nash, tests Luna's limits. He demands Luna give her shares and presidency to Nancy; he sides with Nancy when she destroys Luna's photos; and he covets her Hope Blue Diamond ring, which carries her feelings for Julian. Luna endures, until Leo destroys the mole that made him look identical to Julian.
