Lena overhears a conversation she shouldn't have.

She's sure her new neighbours - the Morgans - are planning a crime.

Her family say she's mistaken.
They are a lovely, friendly couple.

the worse her suspicions.

But Lena hasn't counted on one thing.

A secret from her own past. One the Morgans seem connected to.

And which puts Lena in terrible danger...
