The Dream Team 1989

This morning they were playing ping-pong in the hospital rec room. Now they're lost in New York and framed for murder. This was never covered in group therapy.

Directed by Howard Zieff

Four mental patients on a field trip in New York City must save their caring chaperone, who ends up being taken to a hospital in a coma after accidentally witnessing a murder, before the killers can find him and finish the job.
