A young woman is fated to relive the love of an earlier life. Separated by time, young Serena and botanist Rafael surmount all obstacles as they live a love that is stronger than fate itself. These challenges include the lovely but ambitious Cristina, who is obsessed by the rich botanist and driven nearly mad by her attempts to shatter their great love. A romantic comedy set in the 1940s, Soul Mate underscores the importance of love, family values and the ties of affection with a light touch and plenty of humor.

The story follows the experiences of Marina, a young country bumpkin who marries the mysterious and charismatic widower Roberto Stein, a fabulously wealthy businessman living in 1920s Rio de Janeiro. As Marina attempts to acclimate to her new marriage and responsibilities, she discovers that Stein's late wife, Alice, still seems to have a strong hold over the household. Despite her new husband's affection for her, Marina is nonetheless threatened by Alice's presence, which is made conspicuous through her old maid Juliana's obsessions and her intimidating portrait.
