A mum says severe anxiety has made everyday life a struggle and left her needing financial support. But an anonymous tip-off raises questions about whether the life she has described matches the one she is actually living.

Investigators start digging into Catherine Wieland’s benefit claim, using bank records, social media and covert surveillance to compare what she’s said with what they can prove. The deeper they look, the harder those two versions of her life are to reconcile.
