It's not every day a naked woman climbs out of an abandoned duffel bag in New York's Times Square with your name tattooed across her back. Confusing matters even more, our poor Jane Doe has no memory and the ornate messages that cover her are more cryptic than the instruction manual for an Ikea wardrobe.

Kurt Weller (Sullivan Stapleton; 300: Rise of an Empire), a hardened FBI agent, naturally, is the unlucky man whose name adorns the walking, talking treasure map in Blindspot (premiering in Hong Kong on the same day as in the United States, on Tuesday, at 9.50pm, on Warner TV). And he must decipher the codes before a criminal conspiracy engulfs the pair.

With each situation Jane (Jaimie Alexander; Thor - above) is thrust into, a skill is revealed that offers clues to her past. Having quickly established that she could take down Jason Bourne, should the need arise, the pair attempt to work out how they are connected.

Equal parts Memento, 24 and NCIS, Blindspot begins with an interesting premise and shows plenty of popcorn-scoffing promise, but whether the action will be put on pause long enough for us to explore the suggested inner turmoil of the central characters, it's still too early to tell. While the plot will no doubt take a whole season, or five, to reveal itself, hopefully, by its conclusion, Blindspot won't have drifted into the same dreary romantic territory that Bones did.

Embarking on a very different, but equally absurd hunt this week - across "the most dangerous island in the world" - is an elite team of intrepid explorers searching for a legendary bounty known as the Treasure of the Trinity. This lost stash of Incan gold is said to be worth hundreds of millions of dollars and, following a trail of new evidence, these modern-day tomb raiders head to a plot of land off the coast of Brazil.

Teeming with deadly vipers, Ilha da Queimada Grande is known to the locals as Snake Island. Can the adventurers find the treasure before the pirates, snakes or foul weather find them first?

Treasure Quest: Snake Island (Discovery Channel, tomorrow at 11pm) is sold as a six-part reality-adventure series, but the show bears about as much resemblance to real life as did Indiana Jones' long weekend at the Temple of Doom. Infotainment of the fuzziest sort, the Treasure Quest expedition - from the ship's crew of seasoned "professionals" to the planted artefacts and the clearly trodden paths of the "completely uninhabitable" island - is as fake as my dog's Chewy Vuiton rucksack.

But that, of course, is the point (although I'm not sure Discovery Channel wasn't hoping to trick a few viewers); this mockumentary has clearly been designed to entertain and is as scientifically valuable as a geographical exploration of Hobbiton.

The island itself, however, is the real deal; it's the only known home of the golden lancehead viper - experts say there is one of these deadly serpents for every square metre, and, legend has it, no one bitten by one has ever lived to tell the tale. Hardly the ideal picnic spot.

Following a documentary made by Vice, its then editor-in-chief Rocco Castoro said of Snake Island, "It was like a David Lynch movie, through the prism of Satan's a**hole. The anti-Galapagos. Darwin in reverse."

I'd rather find myself naked in Times Square.
