She's estranged from her only son and his family because he's invited his father to live with him. She's devoted to her dog, Betina, and occupies her spare time as a member of the police force's special senior citizen program. Regina, operating under the code name "Snow White" spends a lot of her time looking for wrongdoers to report to the police. She spends her evenings looking out her apartment window with binoculars into the windows of her neighbors across the street. One night, she watches as an older gentleman appears to give his bedridden wife a lethal injection. She reports it to the police, but they back off when they learn that the gentleman, Carmago (Raul Cortez), is a respected member of the judiciary. Alcides (Luiz Carlos Persy), Regina's police contact, gets so much political flack that he kicks Regina out of the program. But Regina takes it upon herself to continue the investigation on her own. Carmago notices that he's been seeing her around a lot, and, thinking it's a coincidence, asks Regina out on a date. She accepts for the sake of her "investigation," but before long the two find that they are really hitting it off. The Other Side of the Street was co-written and directed by Marcos Bernstein, who co-wrote the script for Central Station, the film that earned Montenegro an Academy Award nomination.
