In this second season, Touch relocates the tension from New York to Los Angeles, to where single dad Martin and his gifted son Jake flee from the mysterious organisation Aster Corps. They meet Lucy, a mother who is looking for her missing, and equaly gifted, teenage daughter Amelia. Subsequently, Martin, Jake and Lucy will look for Amelia together. But, along the way they meet the mathmetical genius, that is posessed by numbers and is a big threat to Jake.
To the readers that haven't seen the first season: you can still start watching season two.
