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?
