The most dangerous thing to want is more.
In the Yorkshire countryside, working-class tomboy Mona meets the exotic, pampered Tamsin. To seal their friendship, Mona introduces Tamsin to her born-again Christian brother and helps her spy on her adulterous father. Bound together by their secrets, the two girls see their friendship deepen and enter into dangerous waters.
