PSi is a dramatic series with hints of comedy that narrates the adventures of Carlo Antonini, a psychiatrist/ psychologist/psychoanalyst who is somewhat pathological and very interventionist, both inside and outside his consulting office. Due to his extreme fascination with cases that lean toward the unconventional, he will suffer consequences in his family life as a father, husband, and friend. The series not only dramatizes the diagnostic and clinical solution of each case but also brings to light the existential issues of modern life.
