Modern families, money and the morals of genetics are just a few of the narrative tensions in Alexis Zegerman's play The Fever Syndrome at Hampstead Theatre.
The family at the centre of the story is that of Richard Myers (Robert Lindsay), an eminent geneticist who now has Parkinson's Disease. He lives in a brownstone in Manhatten with his third wife, Megan (Alexandra Gilbreath), who does her best to care for him.
His grown-up children have returned home to see him presented with a prestigious science award.
His eldest child by his first wife is Dot (Lisa Dillon), who has her husband and 12-year daughter in tow. She is sharp, driven and highly protective of her daughter, who has a rare auto-inflammatory condition called the Fever Syndrome.
Then there are the twins Anthony (Sam Marks) and Thomas (Alex Waldmann) by his second wife. Anthony is charismatic, charming, and an opportunistic investor in Silicon Valley - his latest venture is cryptocurrencies. He's the favourite despite his rare appearances at family gatherings.
Thomas is an artist and has his boyfriend with him. He's the odd one out, not being adept at science and desperately wants approval.
