Senior year means big changes for Bay and Daphne, as the Carlton School for the Deaf receives an influx of hearing students who are not happy to be there. Daphne begins working at a free clinic as part of her probation and Bay takes an art class at a local college.

The fourth season picks up right after graduation with the family and Emmett discovering Bay's impulsive decision - and no one is happy about it. Meanwhile, Daphne is determined to prove herself worthy of her switchster's sacrifice while also dealing with the challenges of a whole new world of college.

In the fifth and final season, Bay and Daphne return home after a transformative 10-month trip to China. Daphne tries to integrate herself back into campus life but finds that things have changed without her. Meanwhile, Bay experiences a setback in her career as a tattoo artist.
