Pinned-down spin, indecipherable web

Film: 'Teen Patti'; Cast: Amitabh Bachchan, Ben Kingsley, R. Madhavan, Raima Sen, Sarah Mohan, Mita Vashist; Director: Leena Yadav; Rating: ***1/2
If you can get over the ludicrousness of a distinguished mathematician, whose god is Albert Einstein and who at the end of the film gets the 'Isaac Newton Award' for excellence in his field, masquerading as a seedy gambler, then 'Teen Patti' is a surprisingly skilful and audaciously complex piece of drama.
It is a tautly-scripted and brilliantly executed film on the deep-rooted link between financial ambitions and moral compromises.
Writer-director Leena Yadav gives the theme of monetary indulgence a dizzying but pinned-down spin. She speeds confidently across out-of-control lives on a college campus with the confident vision of raconteur who spins a seemingly indecipherable web of deceit, intrigue and crime.

Could you please explain to me the emboldened parts?
Though I know "indecipherable" means "unable to be read or understood".
