Intrusive (1986)

The spoiled and insensitive Estrella de Rossi comes across a humble girl, Virginia, who is her spitting image; almost immediately she comes up with a game and, as a bit of mischief, she pays the girl to impersonate her. When she pulls this off successfully and no one notices the change, Estrella goes further and decides to take a year off to go out and live her life. She forces her double to accept this pact and the young village girl is left to assume the role of a rich and married woman, with a husband who is not really hers but who she ends up falling in love with. She will also face an alcoholic mother-in-law, stepchildren in need of attention and love, a company teetering on bankruptcy and above all, the eminent danger of being discovered.
