In High Potential Season 1 Episode 13, "Let's Play," the LAPD's Major Crimes team receives an anonymous email about a hostage, plunging them into a perplexing kidnapping case.

The kidnapper sets up a series of twisted games involving riddles and puzzles that Morgan and her team must solve to save the victims.

This case is different because the kidnapper remains a step ahead, toying with the police and targeting Morgan, even sneaking a threatening message into her bag.

The episode ends without the team catching the culprit, marking the first unsolved case for Morgan and setting up a recurring antagonist for season.
