Signal Rock is an ensemble drama chronicling the days, nights, disappointments, triumphs and other sundry happenings in the lives of the Abakan family and their friends and neighbors in Biri, a small Philippine island community. At the center of the action is Intoy Abakan (Christian Bables), a bit of a troublemaker who enjoys stealing chickens and doesn’t have a job other than doing a little of this and a little of that. The island isn’t overflowing with opportunity.
He lives with his mother and father (Daria Ramirez and Nanding Josef) and equally underemployed brother Joaquin (Arnold Reyes), and all are supported by their sister Vicky (Judy Anne Santos, heard only on the phone), who is living and working in Finland. When Intoy learns his sister is in an abusive relationship and is on the verge of losing custody of her daughter, he summons the entire village to help forge the necessary paperwork to prove Vicky can support her child should she return to the Philippines.
