Okay, so it starts kind of like Hart to Hart.

He's March November, a self-made millionaire and former legendary hitman, who now runs Struthio Security, a wholly legitimate business catering to high-end clients in serious trouble-think being in the cross-hairs of a Nigerian warlord.
He works with Island Chaptal, his girlfriend and partner. She used to be a computer engineer, but a lot of stuff happened, so now she's his CTO and hacks poorly-protected devices and fiber optic cables for him, which kind of sounds like she slept her way to the top, but no, actually.
Together, Island Chaptal and Mr. November fight crime. Mostly. This time though, they're rescuing Joy-Island's BFF-who ended up in a Cancún jail after nearly killing her boyfriend's side chica with a three-feet tall birthday cake. Ancient aliens somehow get involved in this mess, and also a guy name Angel Somoza, who hates sloths. There's gunfights, frenetic capering from Cancún to Cairo, passionate sex, Roomba cats, and a lot of questionable science thrown in.
It's the final chapter of the Spotless series, and just another Monday for March and Island.
