Separation City is a 2009 New Zealand film starring Joel Edgerton, Rhona Mitra, Danielle Cormack, and Les Hill.
[2] Simon (Joel Edgerton) is a decent fellow, married to a lovely woman Pam (Danielle Cormack), living comfortably with two children.
Katrien travels to New Zealand to follow her husband Klaus (Thomas Kretschmann) in an attempt to rekindle their marriage.
Pam sees Simon sneak into the hallway during a speech and hears Katrien's voice on the other end of his phone, figures out what they are doing, and flies back to Wellington angry.
His wife eventually forgives him and as the movie ends, we find that Katrien has accepted a job with an orchestra and lives blocks away from her ex-husband who now takes care of the kids.
