He's invited you in, but will you ever leave?

After Cathy's boyfriend surprisingly ends things she is distraught. She also needs to move out of their flat and find a new place to live.

When a friend tips her off about a room to rent it seems like her luck has suddenly changed.

The house is on one of the city's most sought-after streets and the live-in landlord, whose son has just left home, is charming and kind. Best of all, it's affordable.

Cathy's invited to make herself at home. But there is one rule: she can never go into the garden. Everything else seems so perfect she doesn't think twice.

But she'll soon realise the deal she has made is too good to be true... and now it's far too late...
