On a whim and without resources, Mop and Lucky start a business of their own: Personal Espionage. They set up shop in the only place they can afford, a public storage facility. Unbeknownst to them, this storage facility is actually a lair kept by two Irish-American step-children of the East Coast Mob. As fate would have it, the girls crack their first case. They are officially PES (personal espionage specialists). This new life leads them into bizarre cases, Mob entanglement, personal enlightenment and, of course, dating woes.
