Misbehaviour was released in the United Kingdom on 14 March 2020 by Pathé's distribution partner Walt Disney Studios Motion Pictures through 20th Century Fox.

After helping Jo evade arrest for defacing a sexist billboard advertisement, Jo introduces Sally to her women's group where she is invited to collaborate on the group's messaging and media as part of a planned protest at the 1970 Miss World competition, which is due to take place in London.

Jennifer also befriends Marjorie Johansson (Miss Sweden), the favourite, who confesses to feeling demeaned and exploited by the competition.

Frustrated by the casual sexism she experiences at university, Sally hatches a plan to disrupt the live television broadcast of the Miss World contest by infiltrating the crowd.

Pearl privately confesses to Jennifer that the regime warned her that if she spoke out about the treatment of black South Africans she wouldn't be allowed to return home.

A post-script explains that Jennifer went on to study Political Science and International Relations, later becoming Grenada's High Commissioner to Canada.

The site's critics consensus reads: "Misbehaviour's overall arc will be familiar to fans of feelgood British cinema – and so will the way it triumphs over formula to tell a thoroughly crowd-pleasing story.

[18] Richard Roeper wrote, "Following the playbook of 'The Full Monty,' 'Calendar Girls,' 'Military Wives,' et al., 'Misbehaviour' achieves just the right mix of farcical humor, dry wit and the obligatory dramatic moments when the light banter and sight gags give way to Poignant Confrontations reminding us there are serious undertones to this breezy romp.
