Scientists make a startling discovery in the Antarctic, a Yeti-like snow creature frozen in a block of ice! Meanwhile, Jerry informs Sam, Clover and Alex that there have been reports of a strange being terrorizing a posh ski resort. When they arrive to investigate the luxurious place, they find that they aren't the only ones on the case until they meet Martin Mystery, a teenage paranormal investigator working for the Center – an organization much like WOOHP!

In the B-story, the girls all develop a different relationship with Martin;

Clover was initially hit on by Martin and tried to flirt with him, but got rejected.

Sam was compared to Martin's step-sister, Diana Lombard, much to her annoyance.

Alex started to bond with Martin over their love for video games.
