Chasing the Truth

Chasing the Truth is a Stranger mission in GTA V given to Michael De Santa by the infamous Epsilon Program.

Michael meets Marnie and her friend Jimmy Boston in Grapeseed. They give him a device that they say is used to find extraterestrials. Michael roams around and after many attempts eventually finds an old boot. Michael claims that he is 110% positive that it is what they are looking for and decides to end the search there. Marnie then tells him that he needs to now donate $10,000 to the Epsilon Program website.
