Help! Cannot Remember

Hoping someone may be able to remember a show which was either shown late 70’s or very early 80’s. I have only very limited memory of it as a kid, but trying to track it down but no joy as simply cannot rem enough details 🙁 so hoping someone may know or have few more memories then I do.

The opening scene of the show was something like as a kid hiding from troops (or ‘bad’ people), parents killed, and now he is trying to figure out who killed them etc. Very vague memory of ths how sadly, just want to figure out what it was!

If any idea, or possibles, or anything even remotely linked, let me know and will look up. Was a foreign show shown in NZ either late 70’s or early 80’s.
