Mary goes on a hike with the Buttercups, the group of young girls (like the Girl Scouts) that Alexandria wants to join. Sandra comes along also, thinking that the handsome leader would be there. They all get lost and decide to stay in a cabin until the next day.

Brenda and Lester hear on the radio that a woman escaped from a mental institution and is on the loose in the park. The ladies later hear the same message. When the ladies meet Ranger Granger they assume she is the escaped lunatic disguised as a ranger. When she is sleeping, they tie her up.

That's when the real lunatic showed up. The ladies wind up tying Lucinda Merkle up, and the police take her back to the asylum.
