The third ep of Quantico

The third episode of Quantico has a scene. Taking place at the FBI Academy pool, students are zip tied together at the wrists back to back.

Then they're thrown into the pool, where they're supposed to somehow get each other free.

The heroine and her friend struggle for a bit in the water, until they're able to work each other loose.

There are guys tied up with them, but despite this I thought it was a nice scene. Short and sweet, and taking place in the opening five minutes of the third episode (called "Cover"). Hopefully somebody can make a clip of this.
