Rosamunde Pilcher: Schutzengel(2016)

Overview:

Kate has been in a witness protection program for years because she testified against her own criminal husband Ted Kinnock, putting him behind bars. She lives with her now grown-up son Channing in the county of Cornwall in England. Her son falls in love with young Rachel, the daughter of an aristocratic family. Her parents immediately disapprove of the relationship, as they do not consider Channing worthy of their daughter. When Channing accidentally calls an old contact of his mother's called Dave, events come to a head: Dave was Kate's contact at the police station, but they both fell in love with each other. The policeman now rushes to the island to protect the love of his life, because Ted Kinnock has been released from prison early and is out for revenge.
