When Worlds Collide

After Dr. Bronson (Hayden Rorke) discovers Zyra, a new planet, fellow astronomer Dr. Hendron (Larry Keating) checks Bronson's data and reaches the horrifying conclusion that Bellus, a star in Zyra's orbit, is doomed to crash into the Earth within a matter of months. Meanwhile, Hendron's daughter, Joyce (Barbara Rush), has grown fond of pilot David Randall (Richard Derr), and pleads to have him brought along as a small group is relocated to Zyra to avoid the impending mass destruction.
