Tintorera is a 1977 Mexican-British[1][2] horror film directed by René Cardona Jr. and starring Susan George, Hugo Stiglitz, Fiona Lewis and Andrés García.

Quentin Tarantino paid tribute to this movie at the eighth Morelia International Film Festival, showing a copy from his private collection.

One of the local fishermen and the caretaker of the yacht, Colorado, takes Steven with him when he goes to haul in the sharks he has caught.

Steven is extremely jealous, however, when she begins a relationship with Miguel, a womanizing swimming instructor at the nearby resort hotel.

Miguel introduces Steven to two sisters, American college students Kelly and Cynthia Madison.

They all swim back to shore the next morning, and the submerged tiger shark again chooses not to bother them.

Meanwhile, unbeknownst to Steven or Colonado, the tiger shark attacks another small fishing boat and eats two fishermen.

This time, the tiger shark attacks, ripping Cynthia from Steven's arms as he makes out with her in the water.

Priscilla Barnes, unknown at the time, appears towards the end of the film as a party girl who encounters the shark during night swimming.

The original English dub in theatres and on video featured the voices of Susan George and Fiona Lewis, who played the two British tourists in the film.
