In 'Whose Call is This?', you play as a down-on-their-luck private investigator, Spike Callahan, who has a knack for solving bizarre cases but struggles with personal issues. One fateful evening, Spike receives a mysterious phone call from a past client who vanished without a trace. The catch? The call is routed through a strange, otherworldly network where characters from different dimensions and timelines converge. You must navigate through quirky, unpredictable plot twists and solve puzzles that influence the outcome of the storyline. Every decision you make alters not only the fate of your client but also the colorful cast of oddball characters who join you in unraveling the mystery, from a confused 1950s mobster to an eccentric alien with questionable fashion sense.
