A teenage girl launches a charity for sick children and wins the backing of One Direction – but some parents turn detective when she seeks funds for a life-saving treatment.

Parents turn detective, desperate to prove that Meg isn’t critically ill and that Believe in Magic is built on a lie - but a tragedy makes them question everything they’ve uncovered.

Meg’s funeral is cancelled for a new autopsy, and the sleuths learn that there was no brain tumour. Meg’s half-sister suspects their mother knows more and begins a search for answer.
