Shocked by hardcore porn online, and its impact on their kids' generation, five ordinary mums decide to make their own porn movie.

The mums make the final preparations for the shooting of their porn film, but finding a location and cast is proving harder than they thought. With time almost running out, they finalise their cast and a venue of a warehouse in south east London. There are disagreements during the shoot and tensions are running high - especially as their mentor Erika Lust has promised to help them launch their film if she thinks it's good enough. Later, the mums host a private screening in Soho for friends, family and industry professionals. What do the audience make of the film? And will Erika get behind it?
