Forced to pay off his debt to the murderous Caribbean crime lord, Tariq, instead, the American scuba-diver and treasure hunter, Jackson Slate, wakes up from its deep hibernation a massive, T-Rex-like sauroid off the coast of Belize. Now, Slate has to team up with diver, Henry, happy holidaymakers, Rod and Jane, and the marine biologist, Sarah Jones, to retrieve a Mayan treasure from the dangerous waters; however, the scaly beast from the sea is ever-present and famished. But, what good is a chest full of gold when you're dead? Can Jackson and his team defeat the all-powerful reptile, Poseidon Rex? Written by Nick Riganas

Did You Know?


Belize was formerly the colony of British Honduras. One would expect traffic would be on the left side of the road as in Britain. However at about 52 minutes we see a car with the steering wheel on the left as in most of North and Central America. Belizeans do in fact drive on the right side of the road. See more »


The type of SCUBA regulators that the divers are using in the beginning of the film do not allow for radio communications, yet the divers are talking back and forth to each other and the dive boat. See more »

User Reviews

One of the better SyFy movies, but that's not saying much
1 January 2014 | by KEmerton1992See all my reviews

I have a bad addiction to SyFy original films, and I unfortunately see almost all of them. This one actually had a decent plot and could have been done VERY well if it had a Hollywood (really anything but TV) budget. Out of all of the SyFy movies I have seen, it followed the same basic plot, a giant monster of some kind comes out of the ocean and attacks crappy actors, who were written by crappy writers and directed by a crappy director. But this one wanted SO BADLY to be GOOD! The T-Rex was actually ALMOST really cool looking. It ALMOST didn't look like a teenager in a computer class made him. All in all, it was a decent film, almost like a tribute to Godzilla, not a rip off mind you, because this actually was worth a watch. Three stars out of ten is fair for this, and it should be kept in mind before watching this. Any fan, or not fan, of SyFy, should check this one out!
