The premise of the show had two warring planets settling their differences on Earth secretly. They were to each send 4 or 5 agents who would battle to the last man and the winner would either win their war, or get Earth. The last guy had fallen for an earth woman who (surprise)...

...is an enemy alien in disguise, and kills him at the end.

Any idea what it might have been called?

I'm trying to remember a 70's sci fi TV feature. The premise of the show had two warring planets settling their differences on Earth secretly. They were to each send 4 or 5 agents who would battle to the last man and the winner would either win their war, or get Earth. The last guy had fallen for an earth woman who (surprise)...

...is an enemy alien in disguise, and kills him at the end.

Okay. The premise of the show had two warring planets settling their differences on earth secretly. They were to each send 4 or 5 agents who would battle to the last man...and the winner would either win their war, or get earth. The last guy had fallen for an earth woman who (surprise)  ...

...is an enemy alien in disguise, and kills him at the end.

Any idea what it might have been called? (Sorry, should have said "spoiler alert").
