When Julie Bottomley (Suranne Jones) discovers her husband of 10 years has been sleeping with her sister, her first instinct is to kill him. However, rather than risk life imprisonment herself, she devises a better plan to get revenge on Ian (Dean Lennox Kelly) by faking her own death and framing him for murder. But can she resist the temptation to let her jailed husband know just how "Dead Clever" she's been?

The plot centres on the disappearance of the eponymous Gemma after she goes backpacking with a friend in India. When the friend returns from the trip alone, she is haunted by the belief that Gemma's disappearance is her fault, but mystery surrounds what really happened.
