The Invite is a sex comedy examining how marriage commonly leads to diminished sexual intimacy between partners. The film follows a dinner party between two couples that becomes uncomfortable and revealing. Audiences have responded with powerful, cathartic laughter, experiencing relief at discovering their relationship struggles are widely shared rather than unique failures. Viewers describe feeling seen and unburdened by the film's candid portrayal of marital dysfunction.

The film's framework draws from therapist Esther Perel's work, which argues that American cultural emphasis on duty and contract completion undermines sexual pleasure and exploration. Unlike societies viewing sexuality as integral to family life, American puritanical traditions create shame around desire and position parenthood as the end of sexual activity. This dynamic particularly affects women, who face cultural pressure to prioritise family stability and safety over personal pleasure and continued self-discovery.
