->''A tsunami just flipped the foodchain.''

''Bait'' is an Australian 3D [[ThreateningShark killer shark]] film released in 2012.

In the film, set in a sleepy beach community, shoppers at an underground supermarket are terrorized by a crazed bandit when a tsunami swallows the town. Now trapped, as rushing water threatens to entomb them, the survivors discover that the tsunami has brought an unwanted visitor from the depths.

Originally, a sequel in which a shark terrorizes a flooded school in Los Angeles was in development. In 2013 however, the film was re-conceived as ''Deep Water'' in which a plane crashes in the ocean and its passengers must stay on or onboard to avoid being eaten by sharks. The film is currently on hold.

!!This film includes the following tropes:

* AnArmAndALeg:
** In the opening Rory dies from loss of blood when a shark rips off his legs.
** The security guard who's first to fall victim can still reach for help... until he goes still and ''floats away from his arm.''
* AsianStoreOwner: The supermarket owner is Chinese, but apparently second-generation or later since there's no accent.
* AssholeVictim:
** [[spoiler:Kirby]] is the robber responsible for killing the woman at the start, and tries to use another of the survivors as bait. [[spoiler:Doyle attacks Kirby in turn and uses him as bait instead.]]
** Ditto for [[spoiler: Kyle, the JerkJock]] who was willing to sacrifice his girlfriend's pooch to save his own ass.
* BittersweetEnding: The remaining survivors have managed to escape the sharks and Tina and Josh's relationship seems to be on the mend, but there's still the devastation caused by the tsunami to deal with.
* ContrivedCoincidence: How ''two'' twelve-foot hyper-aggressive Great White Sharks both ended up in the same flooded convenience store is anyone's guess.
* DesolationShot: The movie ends with a wide shot looking over the tsunami-devastated beach town after the survivors escape the shark-infested shopping centre that they were trapped in.
* DisasterMovie: Mixed with a killer shark film.
* EvilDetectingDog: The little dog barks at the submerged car's windows a few seconds before the shark comes into view. Hundreds of birds and another dog become agitated shortly before the tsunami.
* GiantWallOfWateryDoom: The tsunami, which actually kills a ''lot'' more (unnamed) people on-screen than survive to become shark food.
* HalfTheManHeUsedToBe: [[spoiler:Jessup]] is bitten in half by one of the sharks as he is hanging above the water.
* HeroicSacrifice: When an exposed power cord is threatening to almost electrocute everyone if it comes in contact with the water, [[spoiler:Steven]] sacrifices himself to shut off the power.
* HideousHangoverCure: Rory hands Josh a jar with roots and brown liquid (his grandma's special cure) to his hangover in the opening.
* InfantImmortality: Of the animal kind. The dog is alive after it seems at first that it was eaten by a shark. It is, however, averted as well. Before the tsunami hits, we see a little girl having a yellow balloon tied to her wrist by Naomi. After the tsunami has hit, Naomi finds the balloon in the water, with the little girl nowhere to be seen, making her death very apparent. Sheer timing suggests the little girl who's seen being snatched up from the beach as the wave approaches probably didn't make it either.
* JerkAss: Kirby, [[spoiler:making TheReveal that he was the masked robber who put the mask on a convenient corpse to fake his death easy to spot.]]
* JumpScare: [[spoiler: The movie ends with a painfully telegraphed one, when a seagull goes flying out low over the ocean and a third shark lunges out of the water at it and the camera.]]
* MaleGaze: Tina is introduced to the audience with her behind first.
* MySisterIsOffLimits: Rory gives Josh a good-naturedly hard time for proposing to his sister, Tina.
* RecycledInSpace: It's ''Film/DeepBlueSea''... in a supermarket! In fact, this film bears a lot of similarities to a rejected script for a sequel to that movie, called ''Deep Red Sea''. In it, people in a beach town would be menaced by a cluster of sharks after it becomes partly submerged.
* SuperPersistentPredator: The sharks persistently hunt the surviving humans. It becomes more believable at the end when it's revealed that [[spoiler:the sharks were actually ''trapped'' in the convenience store along with the people and couldn't just swim away.]]
* ThreateningShark: The main nemesis. In fact, there are ''two'' of them, a plot point which isn't clear until two thirds of the way through.
* TragicKeepsake: Josh holds on to Rory's necklace after his death.
* TrappedWithMonsterPlot
* TwentyMinutesWithJerks: Par for the course really, but there's this annoying pair of MakeoutKids who get trapped in the carpark and wind up as the B-plot, outliving some of the supermarket survivors.
