It's the year 1959 in Buenos Aires. Mabel, a woman who works in a ministry, travels to a countryside to finalize the signing of a contract for a property. Upon arrival, she encounters characters who are not what they appear to be. The rancher Antonovich, owner of the land, has died, and out of fear of facing justice and losing everything, his wife pretends to be him with the help of a friend, a race car driver. Mabel's arrival complicates their alibi. But the woman's life also becomes complicated. Everything drives her mad, and ultimately, after the tragic death of the pair of friends, she takes the rancher's place to continue the deception.
