The kids are siblings who range in age from six-year-old Leonie (Roma Christensen) to 16-year-old Riley (Karla Crome). They live on a smallholding farm in the Yorkshire countryside with a few chickens, some pigs and an uneasy relationship with their landlord John (Vincent Regan). Their mother Wendy just died of cancer, and they have different fathers -- one of them, Ryan, who's since made the transition to become Mia (Chloë Sevigny), a pre-op woman who learns she has a 11-year-old son who shares her former name and that she's been named the family's legal guardian at the start of the series.
Mia is a ridiculous creation, which works in her favor -- she becomes the touch of the fantastic that unmoors "Hit & Miss" and saves it from being a more mundane kind of quirky makeshift family drama. It's an effect amplified by the fact that Sevigny looks nothing like a man, even a former one who's been carefully learning to live as a woman and taking hormone pills for years. The show first introduces the character in a series of unveilings -- a hooded figure who shoots someone in a parking lot, then goes back to a car where she's shown to be a dark-haired woman who reapplies lipstick in the rearview mirror. And then we see her at home, changing her license plates and then stripping down for the shower to reveal -- yup, an intact penis.
