Born into an upper-class family with a doting mother who foots the bill for her indolent lifestyle, 24-year-old Amanda spends time avoiding work and haunting the local cinematheque in Turin, where she looks for boyfriends but only finds "weird" misfits who mirror her own social situation of being alone every Saturday night. Amanda is lonely but manages to push others away with her awkward and combative personality. She tags along, uninvited, to her much-older housekeeper's family picnics and encourages her school-aged niece to rebel against her mother - Amanda's more responsible and long-suffering older sister, Marina. When Amanda discovers that Rebecca, whom Amanda was close to as a toddler, is back in town, she makes it her mission to convince Marina they are still best-friend material. Initially, Amanda and Rebecca do not seem to have much in common anymore. The latter became a popular high-school athlete and has since studied to become a lawyer. Yet Rebecca's sudden homebound lethargy puts Amanda in the unique position of being comparatively high-functioning, imbuing her small daily dramas and outings with a sense of purpose.
