Barnaby Walker is uptight and has never left the safety of university, where he is studing a seemingly endless art history PhD in Flemish textiles.
No one in his family takes him seriously, so when his father winds up in hospital following a mysterious accident he's determined to save the day by taking over the Walkers' struggling antiques business. He's out to prove himself, but along the way, he discovers secrets about his family that make him question everything he's formerly taken for granted.
Badass bounty hunter Nina Morales isn't afraid of breaking rules (or bones). From the gritty heart of New York City, she's a fiery Puerto Rican whose family comes first.
A breadwinner, she supports her overbearing mother, her directionless niece Sofia, and her cousin Pancho, who's far from the sharpest tool in the shed. She tends to act first and ask questions later, and as a result is often in big trouble.
Barnaby's sister doesn't think rules apply to her. She's never had a proper job or stuck with anything. Due to a mixture of luck, charm and her dad's willingness to bail her out, nothing has ever gone too wrong. Her attractiveness doesn't hurt, either.
Less naive than her brother, Leah knows her father's foibles and is prepared to use them to her advantage. She's also not afraid to screw people over. But the question is: how far will she go? When push comes to shove, is she as ruthless as she likes to think?
Barnaby and Leah's dad Nigel is a wheeler dealer. He gets away with it, though, because he went to the right school and talks the right way.
Ostensibly an upright antiques' dealer, he's bright, charming and good at what he does. From the outside he's the perfect family man, too - with kids, a posh Wimbledon pad and a wife he's been married to for decades. However, he's a man with many secrets. And he's out for himself, more than you could believe.

She puts her wayward daughter's behaviour down to her artistic temperament and believes her husband Nigel is honest and faithful. It's Barnaby who keeps her up at night.
