Flipper

In the first season (ep 20) episode of Flipper called Past Tense, Maya (Jessica Alba) is abducted along with a babysitter played by Elizabeth Lackey and her male friend (Payton Haas).

The kidnapper blames Maya's father for the death of his brother, and so he's taking revenge in a really nasty way.

He ties them up hand and foot to a support column and gags them. He then pours gas all over the marine lab, with the intention of setting it on fire and burning the bound victims alive.

Sheesh! Maybe this dude should just take a deep breath and re-consider his life choices, you know? Maybe go for a walk in the woods, or something?

Elizabeth Lackey goes barefoot throughout the bondage scene, which is very nice.

All three of them are saved, and their rescue is shown in the clip, which you can see right here.
