The definition is at the beginning of the clue.
How the clue works
The definition is Ill-conceived, giving you something erroneous or wrong. For the wordplay, a plastic boyfriend points to KEN (the Barbie doll's other half), on film gives you MIST (a thin filmy layer), and the a from the clue sits in the middle — so MIST plus A plus KEN builds the whole thing up nicely.
