His life would change forever in 1958, when he met Vasilica Gheorghiu, the spoiled daughter of the communist leader Gheorghe Gheorghiu-Dej.
The love story did not last more than a year, as Gheorghe Gheorghiu-Dej got involved by opposing their marriage, on the grounds that Gheorghe Plăcinţeanu's father, a doctor himself, was reposible for the death of Dej’s mother, as he did not admit her to the hospital in Bârlad, although she was ill.
As the measures taken by the security bodies to verify Plăcinţeanu and his family failed to reveal criminal facts, a file was created in which the doctor became an accomplice in a stocking smuggling. It was enough for that time. Gheorghe Plăcinţeanu was detained on August 1, 1959, at the order of Alexandru Drăghici, at a time when the young man was not in the company of his girlfriend, Lica.
The doctor received a sentence of five years of correctional imprisonment, but as this did not ensure the final removal from Lica's life, Alexandru Drăghici, on the orders of the communist leader Gheorghe Gheorghiu-Dej, demanded the further investigation of the convict and his family. While he was imprisoned, Plăcinţeanu was staged with a politicized trial, which was handled by Lieutenant General Vasile Negrea himself.
Thus, the two Plăcinţeanu were tried for conspiracy against the social order. Although the sentence was between 5 and 10 years, the maximum sentence was applied to the two.
Gheorghe Plăcinţeanu was taken to the Râmnicu Sărat Penitentiary, where the most dangerous enemies of the regime were imprisoned, hastening his death, since he had duodenal ulcer and pulmonary TB. He had been kept cold and without food.
