2 sisters.
1 sister possibly lives in Italy with her bf and has passed away.
Her Sister travels to retrieve her things. While she is at the apartment she notices pictures on the fridge with a weird code word on the fridge.
The sisters had a secret language.
Now she's on the hunt to find her sister and believes the boyfriend had something to do with her disappearing.
Maybe she's hiding from him?
