One of those 50s B movies that leaves you wondering why people used to pay for this, and whether they'll open "Giant Shrew Park" on an island some time in the future.
So I wasn't paying a huge amount of attention to the plot, to be honest, but as far as I can tell a trio of scientists made some big ass shrews on an island and then accidentally let them out because they were drunk - seriously, that's what happens. Then a boat arrives and the shit hits the fan (and the shrews bite the legs).
The captain is the hero, and is a drunk ass. As well as the scientists, there's also a Mexican (or... Italian?) guy, a woman (the head scientist's daughter, not sure why she's even here) and the captain's lone crewman. Said crewman is black, so dies immediately, and the rest of the characters spend the rest of the film trying to leave the island. Luckily (and bizarrely) the shrews can't swim, not even so much as to touch their feet to water, so they all take the boat out again. They build a hilarious tank-type thing out of barrels, and shuffle their way to the harbour. It's kind of like that bit in 'Toy Story 2' when they're all crossing the road under traffic cones. All the characters but the lead scientist, his daughter, and the captain die, and we end with the captain saying something along the lines of "now that they're alone they'll eat each other until there's one left, and it'll starve. It's a lesson in over-population" to which the captain replies "talking of overpopulation" and starts making out with his daughter. Yup.
It's pretty shit all around, really. It's enjoyable watching everyone drink and smoke literally the whole time though, and watching the "shrews" (obviously dogs in shaggy coat costumes) run after people and, uh, lick them to death. Oh yeah, the shrews are also venomous, so that's good. We know we're really in trouble towards the end, where they push the drinks cabinet over to block a shrew hole in the wall - never mind the booze!
Personally I think you'd have to be a special kind of odd to really enjoy this, but it has it's moments and is at least legitimately (and unintentionally) funny quite often.
